git blame --textconv is wrongly calling the textconv filter on
symlinks: symlinks are stored as blobs whose content is the target of
the link, and blame calls the textconv filter on a temporary file
filled-in with the content of this blob.
For example:
$ git blame -C -C regular-file.pdf
Error: May not be a PDF file (continuing anyway)
Error: PDF file is damaged - attempting to reconstruct xref table...
Error: Couldn't find trailer dictionary
Error: Couldn't read xref table
Warning: program returned non-zero exit code #1
fatal: unable to read files to diff
That errors come from pdftotext run on symlink.pdf being extracted to
/tmp/ with one-line plain-text content pointing to link destination.
So several failures are demonstrated here:
- git cat-file --textconv :symlink.bin # also HEAD:symlink.bin
- git blame --textconv symlink.bin
- git blame -C -C --textconv regular-file # but also looks on symlink.bin
At present they all fail with something like.
E: /tmp/j3ELEs_symlink.bin is not "binary" file
NOTE: git diff doesn't try to textconv the pathnames, it runs the
textual diff without textconv, which is the expected behavior.

The textconv filter is sometimes incorrectly ran on a temporary file
whose content is the target of a symbolic link, instead of actual file
content. Prepare to test this by marking the content of the file to
convert with "bin:", and let the helper die if "bin:" is not found in
the file content.
NOTE: I've changed $@ to $1 in helper becase textconv program "should
take a single argument" (see Documentation/gitattributes.txt), so
making this more explicit makes sense and also helps to avoid
problems with feeding arguments to echo.

When we're diffing symlinks, we consider the contents to be
the pathname that the symlink points to. When a user sets up
a userdiff driver like "*.pdf diff=pdf", their "diff.pdf.*"
config generally tells us what to do with the content of
pdf files.
With the current code, we will actually process a symlink
like "link.pdf" using a configured pdf driver, meaning we
are using contents which consist of a pathname with
configuration that is expecting contents that consist of an
actual pdf file.
The most noticeable example of this would have been
textconv; however, it was already protected in its own
textconv-specific code path. We can still see the breakage
with something like "diff.*.binary", though. You could
also see it with diff.*.funcname, though it is a bit harder
to trigger accidentally there.
This patch adds a check for S_ISREG lower in the callstack
than the textconv-specific check, which should block use of
any userdiff config for non-regular files. We can drop the
check in the textconv code, which is now redundant.

Generally, trailing space is removed from the string matched by the
xfuncname patterns. The exception is when the matched string exceeds the
length of the fixed-size buffer that it will be copied in to. But, a
string that exceeds the buffer can still contain trailing space in the
portion of the string that will be copied into the buffer. So, simplify
this code slightly, and just perform the trailing space removal always.

This improves the usage output by adding builtin_merge_recursive_usage string
that follows the same pattern used by the other builtin commands.
The previous output for git merger-recursive was:
usage: merge-recursive <base>... -- <head> <remote> ...
Now the output is:
usage: git merge-recursive <base>... -- <head> <remote> ...
Since cmd_merge_recursive is used to handle four different commands we need
the %s in the usage string, so the following example:
$ git merge-subtree -h
Will output:
usage: git merge-subtree <base>... -- <head> <remote> ...

We start the pager too early for several git commands, which results in
the errors sometimes going to the pager rather than show up as errors.
This is often hidden by the fact that we pass in '-X' to less by default,
which causes 'less' to exit for small output, but if you do
export LESS=-S
you can then clearly see the problem by doing
git log --prretty
which shows the error message ("fatal: unrecognized argument: --prretty")
being sent to the pager.
This happens for pretty much all git commands that use USE_PAGER, and then
check arguments separately. But "git diff" does it too early too (even
though it does an explicit setup_pager() call)
This only fixes it for the trivial "git log" family case.

Here "takes no argument" means "does not take an argument". The
latter phrasing might make it clearer that PARSE_OPT_NOARG does not

When people try insane things such as delta-compressing 4GiB files, they
get this assertion:
diff-delta.c:285: create_delta_index: Assertion `packed_entry - (struct index_entry *)mem == entries' failed.
This happens because:
1) the 'entries' variable is an unsigned int
2) it is assigned with entries = (bufsize - 1) / RABIN_WINDOW
(that itself is not a problem unless bufsize > 4G * RABIN_WINDOW)
3) the buffer is indexed from top to bottom starting at
"data = buffer + entries * RABIN_WINDOW" and the multiplication
here does indeed overflows, making the resulting top of the buffer
much lower than expected.
This makes the number of actually produced index entries smaller than
what was computed initially, hence the assertion.
Furthermore, the current delta encoding format cannot represent offsets
into a reference buffer with more than 32 bits anyway. So let's just
limit the number of entries to what the delta format can encode.
