Confirmed with IRIX 6.5 /bin/sh.

Thanks for cleaning up all this. I would like if you could mention the newly
added implicit parameter 'progname' in comments for all functions which need
it, directly or indirectly:

# Input:
# - progname        name of this program

It is not possible to maintain a shell script with dozens of functions
without keeping track of which function uses which variable and which has
side effects on which variables.
