Errors with ltrim and utrim

[jon@…]

Running 0.7-pre on Python 2.1 I get the following backtrace (and just the plain text backtrace, not the usual "there was an error" page).

strip() takes exactly 0 arguments (1 given)
Traceback (most recent call last):

More python2.1 issues.

Fixed in [430], I implemented simple lstrip/rstrip functions that work the same way as in python ≥ python2.2.
