Re: [PATCH 2/2] gitweb: New improved formatting of chunk header in diff

This regresses on hunks of form "@@ -n +m,l @@" and friends, so I dropped it for now.

I've applied other three patches but with manual tweaks while I demangled the linewrap, so please sanity check the result after it mirrors out. I also noticed that we unconditionally give blame link in "diff-tree --name-status" part of commitdiff, so I've fixed it up as well.

I think you still leak control characters in commit messages and htmlized blob text view; and perhaps others like blame. I have made quot_cec into a separate sub that is callable from outside esc_path, so these places should be able to reuse it to make control characters "visible and safe" and keep the presentation consistent. The non-path callers would not feed tabs into the function (I haven't looked at the code but I suspect you would replace them into runs of spaces to the next tab stop by hand), but other controls need to be quoted.
