Subject: Always initialize xpparam_t to 0
X-Git-Tag: v1.6.1-rc1~77^2~3
X-Git-Url: http://git.tremily.us/?a=commitdiff_plain;h=9ccd0a88ac3ea13ac2df4630bfd01c02084f965e;p=git.git

Always initialize xpparam_t to 0

We're going to be adding some parameters to this, so we can't have
any uninitialized data in it.
