fixing minor typos:

        store-procedure my-format-til
                filter-til &gtmotion 'default' 'par -j1 -w70'
        ~endm
        bind-key my-format-til g

not currently: all procedures are interpreted with dobuf(), which is using
the repeat-count for repeating the macro.

format-til is an operator, which uses the repeat-count similarly.

However, the repeat on the procedure will cause a &gtmotion on each
occurrence.  You can work around _that_ by adding a variable to record
the state (though that's clumsy - for instance, you could set the variable
to &stime to record the starting time of the macro, and prompt when it's
a new system-time).

I've considered extending procedures so they could be used to
define operators, rather than building up operators with things
like &gtmotion.  (The hard part seems to be the changes needed
for undo).
