   We made similar changes in our environment, but with one major
   difference. We created a second function called find-tag-exact. This
   function performs the exact match on a word boundary. We did this
   because of the fairly severe penalty you pay for regexp searching over
   string searching (the difference is very noticeable even on a sun4.

I don't entirely understand this.  Matching on a word boundary doesn't
really get the job done, since, say, a "-" is a non-word character.
Thus, "find-file" matches "dired-find-file" on word boundaries.

Also, I don't see how you can avoid the penalty for regexp searching
if you restrict your matches to occur on word boundaries, since that
*is* a regexp search.  If there is some clever trick using string
searches and other tests that's faster than an equivalent regexp
search, then the regexp code needs to be improved!
