MinGW: truncate exit()'s argument to lowest 8 bits
For some reason, MinGW's bash cannot reliably detect failure of the child
process if a negative value is passed to exit(). This fixes it by
truncating the exit code in all calls of exit().
This issue was worked around in run_builtin() of git.c (2488df84
builtin
run_command: do not exit with -1, 2007-11-15). This workaround is no longer
necessary and is reverted.
