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.
