[PATCH] pathspec.c: Fix some sparse warnings

[Ramsay Jones <ramsay@ramsay1.demon.co.uk>]

Sparse issues a warning for all six external symbols defined in this
file. In order to suppress the warnings, we include the 'pathspec.h'
header file, which contains the relevant extern declarations for these
symbols.

Hi Nguyen,

I asked Adam to squash this patch into his 'as/check-ignore' branch
when he next re-rolled the branch. However, it appears that you
resubmitted that branch instead ... :-D

I don't know if this branch is ready to progress to next yet, but
could somebody (yourself, Adam or Jeff?) please squash this into
commit 1a88ae42 ("pathspec.c: move reusable code from builtin/add.c")
before it hits next.

Thanks!

ATB,
Ramsay Jones
