a few code style changes:

    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
