Yeah, change the tabs to spaces.

I couldn't find a good way to do this using the new parser, so now spaces
are ignored on a given line (i.e., you can have as many as you like) but
tabs should only ever occur at the beginning of a line, signaling
indentation.

If you'd like to look at the grammar and lexer and figure a way around
that, fine, but I figured it was a worthy sacrifice for the extra speed,
and actually makes more sense, anyway.  More restrictive, but more
consistent.
