Directory names can contain more different characters than those which
match [\w ] ... and which ones depends on the OS; might as well just
allow anything, and leave it to the OS to complain. Also consider
using line.rstrip() (usually a handy precaution on ANY input text
file) instead of having \s*$ at the end of your regex.

Hmmm ... consider rewriting that as the slightly less obfuscatory
while len(state) > new_level:
state.pop()
If you really want to make the reader slow down and think, try this:
del state[new_level:]
A warning message if there are too many "-" characters might be a good
idea:
[foo]
|-bar
|-zot

And if the input line matches neither regex?

Won't work with the dot on the end.
