Well, I haven't figured out (yet) why this doesn't work (the `!' seems to be
the cause of trouble: map ^A 1G"byG works fine), but I've got a workaround:

	map	^A	:w^M:$r!spell %^M

However, undoing a `^A' reveals another bug: the last line of the original
buffer is doubled! Further undoing leads to `interesting' effects too...
Puzzle for the reader: Who is the connection between vi and csh?
Hint: check recent postings on csh quirks.
Disclaimer: vi's my editor, csh's my shell (sh's for shell scripts).
