In article <1993Jan27.214031.3457@bcars6a8.bnr.ca> djf@bnr.ca asks, among
other things to which I have no answers, this one question to which I do:

!!command              or
!_command              or
:.!command

Hmm.  One could always duplicate the text to be filtered and then filter only
the second copy of it.  Say it's a single line: yyp to duplicate it; the
cursor will then be on the lower of the two identical lines, so !!command to
filter it, leaving the upper line unchanged.  I'm trying to think of some way
to use the :r !command construction (the way one usually adds the output of a
command to the buffer) but I can't figure out how to feed part of the text to
it.  One can use :r !command % to operate on the entire text as most
recentlly written (not necessarily as currently in the buffer).
