gitweb: '--cc' for merges in 'commitdiff' view
Allow choosing between '-c' (combined diff) and '--cc' (compact
combined) diff format in 'commitdiff' view for merge (multiparent)
commits. Default is now '--cc'.
In the bottom part of navigation bar there is link allowing to change
diff format: "combined" for '-c' (when using '--cc') and "compact" for
'--cc' (when using '-c'), just on the right of "raw" link to
'commitdiff_plain" view.
About patchset part of diff --cc output: the difftree (whatchanged
table) has "patch" links to anchors to individual patches (on the same
page). The --cc option further compresses the patch output by
omitting some hunks; when this optimization makes all hunks disappear,
the patch is not shown (like in any other "empty diff" case). But the
fact that patch has been simplified out is not reflected in the raw
(difftree) part of diff output; the raw part is the same for '-c' and
'--cc' options. As correcting difftree is rather out of the question,
as it would require scanning patchset part before writing out
difftree, we add "Simple merge" empty diffs as a place to have anchor
to in place of those simplified out and removed patches.

gitweb: Split git_patchset_body into separate subroutines
This commit makes git_patchset_body easier to read, and reduces level of

git_patchset_body. Also because there are few added comments.
Below there are descriptions of all split-off subroutines:
Separate formatting "git diff" header into format_git_diff_header_line.
While at it fix it so it always escapes pathname. It would be even more
useful if we decide to use `--cc' for merges, and need to generate by
hand empty patches for anchors.

format_extended_diff_header_line. This one is copied without changes.
Separate formatting two-lines from-file/to-file diff header into

Since commit-fb1dde4a we show combined diff for merges in 'commitdiff'

though one would want to see diff to one of merge commit parents. It
is easy in 'commit' view: in the commit header part there are "diff"

'commitdiff' view.
Add to difftree / whatchanged table row with "1", "2", ... links to
'commitdiff' view for diff with n-th parent for merge commits, as a
table header. This is visible only in 'comitdiff' view, and only for
a merge commit (comit with more than one parent).
To save space links are shown as "n", where "n" is number of a parent,
and not as for example shortened (to 7 characters) sha1 of a parent
commit. To make it easier to discover what links is for, each link
has 'title' attribute explaining the link.
Note that one would need to remember that difftree table in 'commit'
view has one less column (it doesn't have "patch" link column), if one
would want to add such table header also in 'commit' view.

Jon Smirl said:
| Once an object reference hits a pack file it is very likely that

This is indeed a good heuristic so here it is. The search always start
with the pack where the last object lookup succeeded. If the wanted
object is not available there then the search continues with the normal
pack ordering.
To test this I split the Linux repository into 66 packs and performed a

follows:
Pack Sort w/o this patch w/ this patch

recent objects last 26.4s 20.9s

limit and object size doesn't match entry->size anymore. This test

2) If pack limit is reached, the object buffer is freed, including when
