gitweb: Fix file name quoting in simplified out patch detection for --cc output

For the --cc (compressed combined) diff output there can be patches which are simple and got simplified out, so there is no patch corresponding to raw output line.

Fix detection of of such simplified out patches: file name in git diff header for --cc diff can be quoted; unquote it.

---
This patch depends _textually_ on the just send
"gitweb: Fix and simplify "split patch" detection"
patch, although it is _conceptually_ independent.

The commit message could be better...

Consistency (kind of). For the ordinary diff output I use m!regexp! instead of simpler /regexp/ to avoid 'leaning toothpicks' syndrome:

m!^diff --git "?a/.*"? "?b/.*"?!

But as it is now not near, then I guess /regexp/ would be better...
