I think it is fine to allow this.

I wonder whether this requires a documentation change.

I think we should continue trying to look at solutions to linespec and
symbol table problems in as language-independent a way as possible.
And, if we can't be language-independent, we should endeavor to have
clean code; the current stuff is still a big mess.

I think Keith's changes will help some here...

Joel> +  p = *argptr;
Joel> +  if (p[0] == '"'

Why only double quotes?

I don't even mind that as a temporary measure.  But I think (or hope)
Keith's plan is for single- and double-quotes to be considered
identically, and uniformly, throughout linespec.
