When multiple regular expressions are concatenated with "\n", they were
traditionally AND'ed together, and only a line that matches _all_ of them
is taken as a match. This however is unwieldy when multiple regexp
feature is used to specify alternatives.
This fixes the semantics to take the first match. A nagative pattern, if
matches, makes the line to fail as before. A match with a positive
pattern will be the final match, and what it captures in $1 is used as the
hunk header comment.
We could write alternatives using "|" in ERE, but the machinery can only
use captured $1 as the hunk header comment (or $0 if there is no match in
$1), so you cannot write:
"junk ( A | B ) | garbage ( C | D )"
and expect both "junk" and "garbage" to get stripped with the existing
code. With this fix, you can write it as:
"junk ( A | B ) \n garbage ( C | D )"
and the way capture works would match the user expectation more
naturally.

Using ERE elements such as "|" (alternation) by backquoting in BRE
is a GNU extension and should not be done in portable programs.

Using this format simplifies the code for completing refs and (in some
cases) improves performance significantly.
For repositories like the current git.git (with more than 200 refs)
there is no real performance difference, but for a repository with 2000
refs the total time needed to complete the refs is reduced by ~25% (from
around 400ms to around 305ms).

Currently, the hunk headers produced by 'diff -p' are customizable by
setting the diff.*.funcname option in the config file. The 'funcname' option
takes a basic regular expression. This functionality was designed using the
GNU regex library which, by default, allows using backslashed versions of
some extended regular expression operators, even in Basic Regular Expression
mode. For example, the following characters, when backslashed, are
interpreted according to the extended regular expression rules: ?, +, and |.
As such, the builtin funcname patterns were created using some extended
regular expression operators.
Other platforms which adhere more strictly to the POSIX spec do not
interpret the backslashed extended RE operators in Basic Regular Expression
mode. This causes the pattern matching for the builtin funcname patterns to
fail on those platforms.
Introduce a new option 'xfuncname' which uses extended regular expressions,
and advertise it _instead_ of funcname. Since most users are on GNU
platforms, the majority of funcname patterns are created and tested there.
Advertising only xfuncname should help to avoid the creation of non-portable
patterns which work with GNU regex but not elsewhere.
Additionally, the extended regular expressions may be less ugly and
complicated compared to the basic RE since many common special operators do
not need to be backslashed.
For example, the GNU Basic RE:
^[ ]*\\(\\(public\\|static\\).*\\)$
becomes the following Extended RE:
^[ ]*((public|static).*)$

There is currently no call to git_config at the start of cmd_archive.
When creating tar archives the core config is read as a side-effect of
reading the tar specific config, but this doesn't happen for zip
archives.
The consequence is that in a configuration with core.autocrlf set,
although files in a tar archive are created with crlf line endings,
files in a zip archive retain unix line endings.

Apparently do_switch() tolerates the lack of escaping in less
funky branch names. For the really strange and scary ones, we
need to escape them properly. It strangely maintains compatible
with the existing handling of branch names with spaces and
exclamation marks.

Textual diff output for unmerged paths was too eager to give condensed
combined diff. Even though "diff -c" (and "diff-files -c -p") is a
request to view combined diff without condensing (otherwise the user would
have explicitly asked for --cc, not -c), we showed "--cc" output anyway.
0fe7c1d (built-in diff: assorted updates, 2006-04-29) claimed to be
careful about doing this, but its breakage was hidden because back then
"git diff" was still a shell script that did not use the codepath it
introduced fully.
