st: Erroneous -fre- command

["Ben Jann" <ben.jann@gmail.com>]

There is a problem with the new -fre- command that has been released
on SSC yesterday. Please don't use it. I will try to fix the problem
and get an update ready as soon as possible.
My apologies,
ben

PS: Thanks to Fred Wolfe for reporting the problem.
