o start function names in column 1
o sort order of flags in getopt and switch
o don't try to reference progname
o unspam some changes introduced by a 2.2.1-R build box instead of a
-current build box
doc changes:
o document when these commands first appeared
o put email address in angle brakets
o minor mdoc clean up
fix a few problems with missing headers, warn called with an exit

these programs now compile -Wall clean (and yes, I know I should use
more than just -Wall) :)
