Ah, I like that approach.

Also, as you mentioned earlier, I think we could drop the quotes.  We'd 
just have to request that quotearg convert spaces into escape sequences.

However, when requesting a special quoting style from quotearg, AFAICT, 
both the quoting style definition and the quoted string require memory 
allocation that isn't required otherwise.  That'll make scan-gram.l a 
little more complicated than the simple invocations we have now.  I also 
want to fix this limitation for some of my offline work that uses 
quotearg, so I may work on a gnulib patch before returning to this issue.
