There's a word endings fuzzy algorithm which works nicely, but is not
exactly the same as an arbitrary prefix match.

I have recently added such prefix matching to htdig. To get reasonable
performance (and any performance at all on very large word indices) it
requires replacing gdbm with a btree database such as Berkeley DB.

I have an unofficial/unsupported patch available for the adventurous,
while I'm awaiting word from Andrew regarding his interest in integrating
my tweaks.
