v04i112: SUPERSEDES v04i111: A convenient spelling filter based on 'spell' (revised)

Posting-number: Volume 4, Issue 112
Submitted-by: "Badri Lokanathan" <badri at ur-valhalla.UUCP>
Archive-name: spell_check.sh

(To the moderator: I posted an earlier version which was incomplete and
buggy; I am not even sure if it reached you. Please cancel it.)
[Superseded; let's see if this works as claimed.  ++bsa]

The following shell script, based on spell, is convenient for highlighting
spelling errors, either in a vi session or stand alone. I wrote it so
that I could pipe text from within a vi session through it.
(Note that you cannot just say
		!}spell
in vi since it would destroy your text!)
[It may anyway.  Many "vi"'s have a bug when large amounts of text are piped
to/from a command.  You have been warned!  ++bsa]
