Subject: transport-helper.c: fix check for (size_t < 0)
X-Git-Tag: v1.7.5-rc0~93
X-Git-Url: http://git.tremily.us/?a=commitdiff_plain;h=803dbdb9686f249e88fae8530b5306d6eea62c1b;p=git.git

transport-helper.c: fix check for (size_t < 0)

'bytes' is of type size_t which is unsigned thus can't be negative.  But
the assigned write() returns ssize_t, and -1 on error.

For testing < 0, 'bytes' needs to be of a signed type.
