Shame. I was hoping for something in, say, Emacs Lisp, that can be invoked
from directly within the editor, operating on a selected region within the
buffer, and bound to a keystroke.

Feel free to write it.  (And an Emacs Lisp function doesn't help me in vim.)

Perhaps I should have mentioned that the Perl script I posted reads from
stdin and writes to stdout.  It can also read from one or more files
named on its command line.

It slurps all its input into memory.  I could have written it to stream
stdin to stdout, which could work better for large inputs, but the
current version works well enough for me.

"shell-command-on-region" is bound to "M-|" (Alt-| or Esc |).
