Cool.  Thanks for the heads up, I hadn't appreciated that ideom until you 
pointed it out.  However, this doesn't help with splitting a multi-command 
bearing variable on `~' for evaluation, when some of the embedded file paths 
include the field separator character.

I'm partway through a merge of MLB into HEAD.  That macro is just a 
placeholder.

I'll apply this consistently after the merge and before the next alpha 
release.
