git-add -i/-p: learn to unwrap C-quoted paths

Browse source 
The underlying plumbing commands are not run with -z option, so the paths
returned from them need to be unquoted as needed.

Remove the now stale BUGS section from git-add documentaiton as suggested
by Teemu Likonen.

Bugs
----
The interactive mode does not work with files whose names contain
characters that need C-quoting. `core.quotepath` configuration can be
used to work this limitation around to some degree, but backslash,
double-quote and control characters will still have problems.
