Always strip trailing whitespace in 'MenuNode.help' and __str__()

Previously, you could get either one or two newlines at the end of
MenuNode.help and the various __str__() methods, though this wasn't
documented.

Always stripping trailing whitespace is cleaner e.g. when using print(),
which automatically appends a trailing newline, and makes things
consistent.

Hopefully nothing relied on the old undocumented behavior. It's fine for
genrest.py at least.
