[PATCH 0/2] Better unquoting of git quoted filenames; esc_path to escape pathnames for display

This series fixes unquote so that it can deal with alphabetic escape sequences like '\n' and '\t', and escaped literal characters like '\"' and '\\', and adds esc_path do deal with the fact that unquoted filenames can now contain control characters, not suitable for HTML. Previous version of unquote was broken in that it did only octal escape sequence unquoting, and could leave filename only partially unquoted.

First patch adds minimal esc_path, second improves esc_path to final version.

Shortlog:
 [PATCH 1/2] gitweb: Better git-unquoting and gitweb-quoting of pathnames
 [PATCH 2/2] gitweb: Use character or octal escape codes (and add span.cntrl) in esc_path
