Subject: Fix uninitialized variable in string_expand_length
X-Git-Url: https://git.tokkee.org/?a=commitdiff_plain;h=2677b744313c939890a8f6b3316f9d5452581ab8;p=tig.git

Fix uninitialized variable in string_expand_length

This led to totally unpredictable results from the function. The style
matches the loop in string_expand.
