Subject: Fix sparse warnings.
X-Git-Tag: v0.99~95
X-Git-Url: https://git.verplant.org/?a=commitdiff_plain;h=6da4016aea2dc5bf311fea160bd8ef96ca82b999;p=git.git

Fix sparse warnings.

Mainly making a lot of local functions and variables be marked "static",
but there was a "zero as NULL" warning in there too.
