[PATCH] setup.c: Fix some "symbol not declared" sparse warnings

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

In particular, sparse issues the "symbol 'a_symbol' was not declared.
Should it be static?" warnings for the following symbols:

    setup.c:159:3: 'pathspec_magic'
    setup.c:176:12: 'prefix_pathspec'

These symbols only require file scope, so we add the static modifier
to their declarations.

Hi Junio,

I noticed these sparse warnings on the next branch (as of a few days
ago).

ATB,
Ramsay Jones
