Replace "gitweb diff header" with its full sha1 of blobs and replace it by "git diff" header and extended diff header. Change also somewhat highlighting of diffs.
Changes:
* "gitweb diff header" which looked for example like below:
file:_<sha1 before>_ -> file:_<sha1 after>_
where 'file' is file type and '<sha1>' is full sha1 of blob is
changed to
diff --git _a/<file before>_ _b/<file after>_
In both cases links are visible and use default link style. If file
is added, a/<file> is not hyperlinked, if file is deleted, b/<file>
is not hyperlinked.
* there is added "extended diff header", with <path> and <hash>
hyperlinked (and <hash> shortened to 7 characters), and <mode>
explained: '<mode>' is extended to '<mode> (<file type>)'.
* <file> hyperlinking should work also when <file> is originally
quoted. For now we present filename quoted. This needed changes to
parse_difftree_raw_line subroutine. And doesn't work: perhaps
unquote is broken.
* from-file/to-file two-line header lines have slightly darker color
than removed/added lines.
* chunk header has now delicate line above for easier finding chunk
boundary, and top margin of 1px.WORK IN PROGRESS: might not work (and actually doesn't work correctly) for strange filenames, i.e. filenames contaning either metacharacters or having TAB, LF, backslash or doublequote in them.
Code should be much more clean, by the way.
