When doing a combined diff, we did not respect textconv attributes at
all. This generally lead to us printing "Binary files differ" when we
could show a combined diff of the converted text.
This patch converts file contents according to textconv attributes. The
implementation is slightly ugly; because the textconv code is tightly
linked with the diff_filespec code, we temporarily create a diff_filespec
during conversion. In practice, though, this should not create a
performance problem.

This function actually does two things:
1. Load the userdiff driver for the filespec.
2. Decide whether the driver has a textconv component, and
initialize the textconv cache if applicable.
Only part (1) requires the filespec object, and some callers
may not have a filespec at all. So let's split them it into
two functions, and put part (2) with the userdiff code,
which is a better fit.

The combined diff code path is totally different from the
regular diff code path, and didn't handle binary files at
all. The results of a combined diff on a binary file could
range from annoying (since we spewed binary garbage,
possibly upsetting the user's terminal), to wrong (embedded
NULs caused us to show incorrect diffs, with lines truncated
at the NUL character), to potential security problems
(embedded NULs could interfere with "-z" output, possibly
defeating policy hooks which parse diff output).
Instead, we consider a combined diff to be binary if any of
the input blobs is binary. To show a binary combined diff,
we indicate "Binary blobs differ"; the "index" meta line
will show which parents had which blob.

One loop combined both the patch generation and checking
whether there was any mode change to report. Let's factor
that into two separate loops, as we may care about the mode
change even if we are not generating patches (e.g., because
we are showing a binary diff, which will come in a future
patch).

This is a pretty big logical chunk, so it makes the function
a bit more readable to have it split out. In addition, it
will make it easier to add an alternate code path for binary
diffs in a future patch.

A naive method of treating BEGIN/END blocks with a brace on the second
line as diff/grep funcname context involves also matching unrelated
lines that consist of all-caps letters:
sub foo {
print <<'EOF'
text goes here
...
EOF
... rest of foo ...
}
That's not so great, because it means that "git diff" and "git grep
--show-function" would write "=EOF" or "@@ EOF" as context instead of
a more useful reminder like "@@ sub foo {".
To avoid this, tighten the pattern to only match the special block
names that perl accepts (namely BEGIN, END, INIT, CHECK, UNITCHECK,
AUTOLOAD, and DESTROY). The list is taken from perl's toke.c.

A command exiting with the expected status is not particularly

While the indication of progress might be useful when tracking down
where in a test a failure has happened, the same applies to most other
test helpers, which are quiet about success, so this single helper's
output stands out in an unpleasant way. An alternative method for
showing progress information might to invent a --progress option that
runs tests with "set -x", or until that is available, to run tests
using commands like
prove -v -j2 --shuffle --exec='sh -x' t2202-add-addremove.sh

Accept
sub foo
{
}
as an alternative to a more common style that introduces perl
functions with a brace on the first line (and likewise for BEGIN/END
blocks). The new regex is a little hairy to avoid matching
# forward declaration
sub foo;
while continuing to match "sub foo($;@) {" and
sub foo { # This routine is interesting;
# in fact, the lines below explain how...
While at it, pay attention to Perl 5.14's "package foo {" syntax as an
alternative to the traditional "package foo;".

The builtin perl userdiff driver is not greedy enough about catching
POD header lines. Capture the whole line, so instead of just
declaring that we are in some "@@ =head1" section, diff/grep output
can explain that the enclosing section is about "@@ =head1 OPTIONS".

The userdiff funcname mechanism has no concept of nested scopes ---
instead, "git diff" and "git grep --show-function" simply label the
diff header with the most recent matching line. Unfortunately that
means text following a subroutine in a POD section:
=head1 DESCRIPTION
You might use this facility like so:
sub example {
foo;
}
Now, having said that, let's say more about the facility.
Blah blah blah ... etc etc.
gets the subroutine name instead of the POD header in its diff/grep
funcname header, making it harder to get oriented when reading a
diff without enough context.
The fix is simple: anchor the funcname syntax to the left margin so
nested subroutines and packages like this won't get picked up. (The
builtin C++ funcname pattern already does the same thing.) This means
the userdiff driver will misparse the idiom
{
my $static;
sub foo {
... use $static ...
}
}
but I think that's worth it; we can revisit this later if the userdiff
mechanism learns to keep track of the beginning and end of nested
scopes.

Introduce a test_expect_funcname function to make a diff and apply a
regexp anchored on the left to the function name it writes, avoiding
some repetition.
Omit the space after >, <<, and < operators for consistency with
other scripts. Quote the <<here document delimiter and $ signs in
quotes so readers don't have to worry about the effect of shell
metacharacters.
Remove some unnecessary blank lines.
Run "git diff" as a separate command instead of as upstream of a pipe
that checks its output, so the exit status can be tested. In
particular, this way if "git diff" starts segfaulting the test harness
will notice.
Allow "error:" as a synonym for "fatal:" when checking error messages,
since whether a command uses die() or "return error()" is a small
implementation detail.
Anchor some more regexes on the right.
None of the above is very important on its own; the point is just to
make the script a little easier to read and the code less scary to
modify.

Introduce a "test_config" function to set a configuration variable
for use by a single test (automatically unsetting it when the
assertion finishes). If this function is used consistently, the
configuration used in a test_expect_success block can be read at the
beginning of that block instead of requiring reading all the tests
that come before. So it becomes a little easier to add new tests or
rearrange existing ones without fear of breaking configuration.
In particular, the test of alternation in xfuncname patterns also
checks that xfuncname takes precedence over funcname variable as a
sort of side-effect, since the latter leaks in from previous tests.
In the new syntax, the test has to say explicitly what variables it is
using, making the test clearer and a future regression in coverage
from carelessly editing the script less likely.

Most, but not all, tests in this script rely on attributes declaring
that files with a .java extension should use the "java" driver:
*.java diff=java
Split out a "set up" test to put such a .gitattributes in place after
the tests that do not want it have run, to make it more likely that
individual tests other than this setup test can be safely modified,
rearranged, or skipped. Presumably this setup code will learn to
request other drivers for other extensions in the same place when the
test suite learns to exercise other diff drivers.
Similarly, make sure that early test assertions that do not use these
default attributes set up .gitattributes appropriately for themselves,
so tests that run before can be modified with less risk of breaking
something.
