Diff to previous 1.28 (colored)

Change the exit value on errors to be more 4.4BSD like. Use the sum of
errors up to a maximum of 127, then to do not increment anymore,
though programme execution continues.

Use 127 as a maximum because error codes above this are:

1. bad because of signed bugs in programs.
2. used as the traditional shell $? representation of "kill by signal"
   where $? = 128 + signal.
