This error message needs to better delineate the file name.
One could either put it in quotes (and escape internal quotes),
or change it to something like:
No such source file: file with spaces -line 10.

I'm still really uneasy with supporting
b -source file with spaces -line 20

This is intended to be the low-level access to specifying locations.
Low level APIs shouldn't be too concerned with easing typing.

It's easier to relax restrictions than impose them after the fact.
Can we require such files to be quoted today,
and then later relax the restriction if there's a compelling
reason to do so?
