Subject: tools/wrap-commit-msg.py: fix file truncation
X-Git-Tag: v1.1.0~37
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=00794a93eccb7299942bd833df83d6756e6b7463;p=libvpx

tools/wrap-commit-msg.py: fix file truncation

truncate() operates from the current file pointer position. On at least
Linux specifying 0 without resetting the pointer will pad the file with
zeros to the current offset.
