Subject: Fix init_statefile to not use optarg.
X-Git-Url: https://www.chiark.greenend.org.uk/ucgi/~bjharris/git?a=commitdiff_plain;h=e1a9b5de99e8da457fea03efa2d27e43175cfbb9;p=clunk.git

Fix init_statefile to not use optarg.

I failed to update it to use a local variable when I moved it out of
init().
