There is no point to this. Either:
1. The program has already loaded git_diff_ui_config, in
which case this is a noop.
2. The program didn't, which means it is plumbing that
does not _want_ git_diff_ui_config to be loaded.

The funcname patterns influence the "comment" on @@ lines of
the diff. They are safe to use with plumbing since they
don't fundamentally change the meaning of the diff in any
way.
Since all diff users call either diff_ui_config or
diff_basic_config, we can get rid of the lazy reading of the
config.

The diff porcelain uses git_diff_ui_config to set
porcelain-ish config options, like automatically turning on
color. The plumbing specifically avoids calling this
function, since it doesn't want things like automatic color
or rename detection.
However, some diff options should be set for both plumbing
and porcelain. For example, one can still turn on color in
git-diff-files using the --color command line option. This
means we want the color config from color.diff.* (so that
once color is on, we use the user's preferred scheme), but
_not_ the color.diff variable.
We split the diff config into "ui" and "basic", where
"basic" is suitable for use by plumbing (so _most_ things
affecting the output should still go into the "ui" part).

Recent check_ref_format() returns -3 as well as -1 (general
error) and -2 (less than two levels). The caller was explicitly
checking for -1, to allow "HEAD" but still needed to disallow
bogus refs.
This introduces symbolic constants for the return values from
check_ref_format() to make them read better and more
meaningful. Normal ref creation codepath can still treat
non-zero return values as errors.

The config parsing routines use the static global
'config_file' to store the FILE* pointing to the current
config file being parsed. The function get_next_char()
automatically converts an EOF on this file to a newline for
the convenience of its callers, and it sets config_file to
NULL to indicate that EOF was reached.
This throws away useful information, though, since some
routines want to call ftell on 'config_file' to find out
exactly _where_ the routine ended. In the case of a key
ending at EOF boundary, we ended up segfaulting in some
cases (changing that key or adding another key in its
section), or failing to provide the necessary newline
(adding a new section).
This patch adds a new flag to indicate EOF and uses that
instead of setting config_file to NULL. It also makes sure
to add newlines where necessary for truncated input. All
three included tests fail without the patch.

After replaying a single change, the code performed a number of checks,

The commit message template when squashing multiple commits is

When "git pull --tags" is run without any other arguments, the
standard error message "You told me to fetch and merge stuff but
there is nothing to merge! You might want to fix your config"
is given.
While the error may be technically correct, fixing the config
would not help, as "git pull --tags" itself tells "git fetch"
not to use the configured refspecs.
This commit makes "git pull --tags" to issue a different error
message to avoid confusion. This is merely an interim solution.
In the longer term, it would be a better approach to change the
semantics of --tags option to make "git fetch" and "git pull"
to:
(1) behave as if no --tags was given (so an explicit refspec on
the command line overrides configured ones, or no explicit
refspecs on the command line takes configured ones); but
(2) no auto-following of tags is made even when using
configured refspecs; and
(3) fetch all tags as not-for-merge entries".
Then we would not need to have this separate error message, as
the ordinary merge will happen even with the --tags option.

If a config file has become mildly corrupted due to a missing LF
we may discover some other option joined up against the end of a
numeric value. For example:
[section]
number = 1auto
where the "auto" flag was meant to occur on the next line, below
"number", but the missing LF has caused it to no longer be its
own option. Instead the word "auto" is parsed as a 'unit factor'
for the value of "number".
Before this change we got the confusing error message:
fatal: unknown unit: 'auto'
which told us nothing about where the problem appeared. Now we get:
fatal: bad config value for 'aninvalid.unit'
which at least points the user in the right direction of where to
search for the incorrectly formatted configuration file.
Noticed by erikh on #git, which received the original error from
a simple `git checkout -b` due to a midly corrupted config.

Although we traditionally stripped away excess blank lines, trailing
whitespaces and lines that begin with "#" from the commit log message,
sometimes the message just has to be the way user wants it.
For instance, a commit message template can contain lines that begin with
"#", the message must be kept as close to its original source as possible
if you are converting from a foreign SCM, or maybe the message has a shell
script including its comments for future reference.
The cleanup modes are default, verbatim, whitespace and strip. The
default mode depends on if the message is being edited and will either
strip whitespace and comments (if editor active) or just strip the
whitespace (for where the message is given explicitely).
