[vile] Using filter-til to replace format-til

[Jānis Rūcis]

Hello,

I'm trying to create a binding that would work in a manner similar to
format-til, while instead using an external program to do the
formatting.  This is basically what filter-til already does, except I
can't figure out how to avoid typing the command every time I use it.

The closest I've got (basic idea) is this:

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

But this handles a repeat count in strange ways, not the same way
format-til and filter-til do.  Is there a way I can obtain the repeat
count from within the macro to pass to filter-til?
