Subject: builtin run_command: do not exit with -1.
X-Git-Tag: v1.5.4-rc0~154^2~6
X-Git-Url: http://git.tremily.us/?a=commitdiff_plain;h=2488df84;p=git.git

builtin run_command: do not exit with -1.

There are shells that do not correctly detect an exit code of -1 as a
failure. We simply truncate the status code to the lower 8 bits.
