Just noticed this while cleaning up the display for do_morphstat.
If you check in tables.c you will notice that BOTH do_morphlist and do_revert are missing. Additionally, mud.h is missing the entry for do_morphlist, although oddly enough do_revert is actually in there.
Just figured this might be useful information in case anyone actually uses the polymorph stuff. I'm surprised this hasn't been mentioned before.
Anyway, hope someone finds this helpful.
