Some multi-byte encoding can have a backslash byte as a later part

* sk/gitweb-highlight-encoding:
gitweb: apply fallback encoding before highlight
Some multi-byte character encodings (such as Shift_JIS and GBK) have
characters whose final bytes is an ASCII '\' (0x5c), and they
will be displayed as funny-characters even if $fallback_encoding is
correct. This is because `highlight` command always expects UTF-8
encoded strings from STDIN.
$ echo 'my $v = "申";' | highlight --syntax perl | w3m -T text/html -dump
my $v = "申";
$ echo 'my $v = "申";' | iconv -f UTF-8 -t Shift_JIS | highlight \
--syntax perl | iconv -f Shift_JIS -t UTF-8 | w3m -T text/html -dump

git_object() chomps $type that is read from "cat-file -t", but
it does so before checking if $type is defined, resulting in
a Perl warning in the server error log:
gitweb.cgi: Use of uninitialized value $type in scalar chomp at

when trying to access a non-existing commit, for example:

Check the value in $type before chomping. This will cause us to
call href with its action parameter set to undef when formulating
the URL to redirect to, but that is harmless, as the function treats
a parameter that set to undef as if it does not exist.

As of CGI.pm's 4.08 release, the behavior to call
CGI::param() in a list context is deprecated (because it can
be potentially unsafe if called inside a hash constructor).
This causes gitweb to issue a warning for some of our code,
which in turn causes the tests to fail.
Our use is in fact _not_ one of the dangerous cases, as we
are intentionally using a list context. The recommended
route by 4.08 is to use the new CGI::multi_param() call to
make it explicit that we know what we are doing.
However, that function is only available in 4.08, which is
about a month old; we cannot rely on having it.
One option would be to set $CGI::LIST_CONTEXT_WARN globally,
which turns off the warning. However, that would eliminate
the protection these newer releases are trying to provide.
We want to annotate each site as OK using the new function.
So instead, let's check whether CGI provides the
multi_param() function, and if not, provide an
implementation that just wraps param(). That will work on
both old and new versions of CGI. Sadly, we cannot just
check defined(\&CGI::multi_param), because CGI uses the
autoload feature, which claims that all functions are
defined. Instead, we just do a version check.

Change the @author_initials feature Jakub added in
v1.6.4-rc2-14-ga36817b to match non-ASCII author initials as intended.
The regexp Jakub added was intended to match
non-ASCII (/\b([[:upper:]])\B/g). But in Perl this doesn't actually
match non-ASCII upper-case characters unless the string being matched
against has the UTF8 flag.
So when we open a pipe to "git blame" we need to mark the file
descriptor we're opening as utf8 explicitly.
So as a result it abbreviates me to "AB" not "ÆAB", entirely because "Æ"
isn't /[[:upper:]]/ unless the string being matched against has the UTF8
flag.
Here's something that demonstrates the issue:
#!/usr/bin/env perl
use strict;
use warnings;
binmode STDOUT, ':utf8' if $ENV{UTF8};
open my $fd, "-|", "git", "blame", "--incremental", "--", "Makefile" or die "Can't open: $!";
binmode $fd, ":utf8" if $ENV{UTF8};
while (my $line = <$fd>) {
next unless my ($author) = $line =~ /^author (.*)/;
my @author_initials = ($author =~ /\b([[:upper:]])\B/g);
printf "%s (%s)\n", join("", @author_initials), $author;
}
When that's run with and without UTF8 being true in the environment it
gives, on git.git:
$ UTF8=0 perl author-initials.pl | sort | uniq -c |

gitweb: URL-decode $my_url/$my_uri when stripping PATH_INFO
When gitweb is used as a DirectoryIndex, it attempts to strip
PATH_INFO on its own, as $cgi->url() fails to do so.
However, it fails to account for the fact that PATH_INFO has
already been URL-decoded by the web server, but the value
returned by $cgi->url() has not been. This causes the stripping
to fail whenever the URL contains encoded characters.
To see this in action, setup gitweb as a DirectoryIndex and
then use it on a repository with a directory containing a
space in the name. Navigate to tree view, examine the gitweb
generated html and you'll see a link such as:
<a href="/test.git/tree/HEAD:/directory with spaces">directory with spaces</a>
When clicked on, the browser will URL-encode this link, giving
a $cgi->url() of the form:
/test.git/tree/HEAD:/directory%20with%20spaces
While PATH_INFO is:
/test.git/tree/HEAD:/directory with spaces
Fix this by calling unescape() on both $my_url and $my_uri before
stripping PATH_INFO from them.

When we see a signed-off-by line (and its friends), we set $signoff

giving control to the rest of the loop. And when the line we saw is
not a signed-off-by line, we reset $signoff to false before running
the remainder of the loop.
Hence, the check for $signoff that attempts to remove an extra empty
line between two signed-off-by line was not doing anything useful.
Rename $empty to a more explicit name $skip_blank_line to tell us to
skip a blank line when we see one, set it after we see and emit a
blank line (to avoid showing more than one empty lines in a raw) or

gitweb: add If-Modified-Since handling to git_snapshot().

gitweb: add `status` headers to git_feed() responses.
The highlightning of combined diffs is currently disabled. This is
because output from a combined diff is much harder to highlight because
it is not obvious which removed and added lines should be compared.
Current code requires that the number of added lines is equal to the
number of removed lines and only skips first +/- character, treating
second +/- as a line content, Thus, it is not possible to simply use
existing algorithm unchanged for combined diffs.
Let's start with a simple case: only highlight changes that come from
one parent, i.e. when every removed line has a corresponding added line
for the same parent. This way the highlightning cannot get wrong. For
example, following diffs would be highlighted:
- removed line for first parent
+ added line for first parent
context line
-removed line for second parent
+added line for second parent
or
- removed line for first parent
-removed line for second parent
+ added line for first parent
+added line for second parent
but following output will not:
- removed line for first parent
-removed line for second parent
+added line for second parent
++added line for both parents
In other words, we require that pattern of '-'-es in pre-image matches
pattern of '+'-es in post-image.

handles combined diffs.

Reading diff output is sometimes very hard, even if it's colored,
especially if lines differ only in few characters. This is often true
when a commit fixes a typo or renames some variables or functions.
This commit teaches gitweb to highlight characters that are different
between old and new line with a light green/red background. This should
work in the similar manner as in Trac or GitHub.
The algorithm that compares lines is based on contrib/diff-highlight.
Basically, it works by determining common prefix/suffix of corresponding
lines and highlightning only the middle part of lines. For more
information, see contrib/diff-highlight/README.
Combined diffs are not supported but a following commit will change it.

Now lines are formatted closer to place where we actually use HTML
formatted output.
This means that we put raw lines in the @chunk accumulator, rather than
formatted lines. Because we still need to know class (type) of line
when accumulating data to post-process and print, process_diff_line()
subroutine was retired and replaced by diff_line_class() used in
git_patchset_body() and new restructured format_diff_line() used in
print_diff_chunk().
As a side effect, we have to pass \%from and \%to down to callstack.
This is a preparation patch for diff refinement highlightning. It's not
