Looks syslog() is bombing if "words" is NULL. Adding a check for a NULL "words"
parameter appears to solve the problem. Here's a patch.

Hi, all.
On our site htsearch occasionally throws server errors when called directly (eg enter
/cgi-bin/htsearch in your browser instead of submitting the search form). I finally
had some time to dig into it.
This appears to be a bug related to setting logging=true. Turning off logging in the
config file produces the expected result (a "No matches" page).
Gory details: Solaris 9, htdig 3.1.6 2001-09-03 snapshot compiled with gcc 2.8.1.
Stack backtrace from gdb:
(gdb) bt

If there's any other info I can provide, let me know.
