There's one additional thing going on.  When you use BOTH -a and -m,
then anything found in the hash table with -m is searched for AGAIN by
-a, using the name as found in the hash table rather than the pattern
supplied as the -m argument.   This is why "zsh" shows up multiple
times but your garbled-name scripts do not.
