Fix two whitespace bugs in the lexer.

Browse source 
The first bug was not allowing whitespace between '#' and the
directive name.

The second bug was swallowing a terminating newline along with any
trailing whitespace on a line.

With these two fixes, and the previous commit to stop emitting SPACE
tokens, the recently added extra-whitespace test now passes.
