Some files in git.git contain lines that look like conflict markers,
either in examples or tests, or in the case of Documentation/gitk.txt
because of the asciidoc heading.
Having conflict markers the same length as the actual content can be
confusing for humans, and is impossible to handle for tools like 'git
rerere'. Work around that by setting the 'conflict-marker-size'
attribute for those files to 32, which makes the conflict markers
unambiguous.

Declare that the *.py files in our tree are Python for the purposes of
diffing, and as in 00ddc9d13c ("Fix build with core.autocrlf=true",
2017-05-09) set eol=lf on them, which makes sense like with the *.perl
files.

As noted in gitattributes(5) this gives better patch context for these
types of files.

Change the list of Perl extensions added in 00ddc9d13c ("Fix build
with core.autocrlf=true", 2017-05-09) to also include *.pl, we have
some of those in the tree, e.g. in t/.

On Windows, the default line endings are denoted by a Carriage Return
byte followed by a Line Feed byte, while Linux and MacOSX use a single
Line Feed byte to denote a line ending.
To help with this situation, Git introduced several mechanisms over the
last decade, most prominently the `core.autocrlf` setting.
Sometimes, however, a single setting is incorrect, e.g. when certain
files in the source code are to be consumed by software that can handle
only LF line endings, while other files can use whatever is appropriate
for the current platform.
To allow for that, Git added the `eol` option to its .gitattributes
handling, expecting every user of Git to mark their source code
appropriately.
Bash assumes that line-endings of scripts are denoted by a single Line
Feed byte. Therefore, shell scripts in Git's source code are one example
where that `eol=lf` option is *required*.
When generating common-cmds.h, the Unix tools we use generally operate on
the assumption that input and output deliminate their lines using LF-only
line endings. Consequently, they would happily copy the CR byte verbatim
into the strings in common-cmds.h, which in turn makes the C preprocessor
barf (that interprets them as MacOS-style line endings). Therefore, we
have to mark the input files as LF-only: command-list.txt and
Documentation/git-*.txt.
Quite a bit belatedly, this patch brings Git's own source code in line
with those expectations by setting those attributes to allow for a
correct build even when core.autocrlf=true.
This patch can be validated even on Linux, by using this cadence:
git config core.autocrlf true
rm .git/index && git stash
make -j15 DEVELOPER=1

Set the diff attribute for C source file to "cpp" in order to improve
git's ability to determine hunk headers. In particular it helps avoid
showing unindented labels in hunk headers. That in turn is useful for
git diff -W and git grep -W, which show whole functions now instead of
stopping at a label.

When a CR is accidentally added at the end of a C source file in the git
project tree, "git diff --check" doesn't detect it as an error.
$ echo abQ | tr Q '\015' >>fast-import.c
$ git diff --check
I think this is because the "whitespace" attribute is set to *.[ch] files
without specifying what kind of errors are caught. It makes git "notice
all types of errors" (as described in the documentation), but I think it
is incorrectly setting cr-at-eol, too, and hides this error.

This establishes what the "bad" whitespaces are for this
project.
The rules are:
- Unless otherwise specified, indent with SP that could be
replaced with HT are not "bad". But SP before HT in the
indent is "bad", and trailing whitespaces are "bad".
- For C source files, initial indent by SP that can be replaced
with HT is also "bad".
- Test scripts in t/ and test vectors in its subdirectories can
contain anything, so we make it unrestricted for now.
Anything "bad" will be shown in WHITESPACE error indicator in
diff output, and "apply --whitespace=warn" will warn about it.
