Subject: Initialize 'o' just in case.
X-Git-Tag: v1.2~14
X-Git-Url: http://git.neil.brown.name/?a=commitdiff_plain;h=0de847b3717d8bb97b7d73d203acb4ffae16381b;p=wiggle.git

Initialize 'o' just in case.

Some compilers complain that this might be used
uninitialised.  They are wrong as it is only used when 'found' is
non-zero, and it is always set before found is set, but
as I like -Werror, I need to handle bad warnings too.

Fixes #6
