[nimh-dev] options and getopt

[Joel Uckelman <uckelman@xxxxxxxxx>]

How do we want to handle options? nmh commands take options with single
hyphens, e.g. '-reverse'. Unfortunately, getopt interprets this as bundled
short options, so '-reverse', '-eeerrsv', and '-r -e -v -e -r -s -e' are all
equivalent.

I think we have three options (heh!):

1. Switch to long options, e.g. '--reverse'. We can use getopt, but this
breaks compatibility with nmh.

2. Write our own option parser. This maintains nmh compatibility, but
keeps us using a wierd non-standard option format and makes us write
more code.

3. Use getopt, but check for anagrams. This would work so long as no two
distince options for the same command are anagrams of each other. (Yech!)
