[PATCH] revision.c: Fix a sparse warning

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

Sparse issues an "'sole_interesting' not declared. Should it be static?"
warning. In order to suppress the warning, since this symbol does not
need more than file visibility, we simply add the static modifier to
its declaration.

Hi Kevin,

If you need to re-roll your 'kb/full-history-compute-treesame-carefully'
branch, could you please squash this into commit 039bdad1 ("revision.c:
discount UNINTERESTING parents", 30-04-2013).

Thanks!

ATB,
Ramsay Jones
