git-apply:--include=pathspec

Browse source 
This allows --include=pathspec, similar to --exclude=pathspec.

The rule when one or both of these are used is that the include/exclude
patterns are examined in the order they are given on the command line, and
the first match determines if a patch to each path is used or not.  Hence:

    $ git apply --include='specific.h' --exclude='*.h' <diff

would apply the patch to specific.h header file, but all other patches in
the input file to other header files are ignored.  A patch to a path that
does not match any include/exclude pattern is used by default if there is
no include pattern on the command line, and ignored if there is any
include pattern.

This originally came from Joe Perches, but both the design of the
semantics and the implementation have been redone complately.

When --exclude and --include patterns are used, they are examined in the
order they appear on the command line, and the first match determines if a
patch to each path is used. A patch to a path that does not match any
include/exclude pattern is used by default if there is no include pattern
on the command line, and ignored if there is any include pattern.

When applying a patch, detect a new or modified line that has
