Please, apply attached patch for contrib/tsearch to 7.2.1 and current
CVS. It  fix english stemmer's problem with ending words like
'technology'.

We have found one more bug in english stemmer. The bug is with
'irregular'  english words like 'skies' -> 'sky'. Please, apply attached
cumulative patch to  7.2.1 and current CVS instead previous one.

Thank to Thomas T. Thai <tom@minnesota.com> for hard testing. This kind
of bug  has significance only for dump/reload database and viewing, but
searching/indexing works right.
