Strip whitespace at the end of <?python ?> blocks

[Dale Sedivec <dale-keyword-genshi.e8bcba@…>]

A line containing nothing but whitespace at the end of a <?python> PI raises a syntax error:

>>> from genshi.template import MarkupTemplate
>>> tmpl = MarkupTemplate("<foo><?python print 'hi'\n ?></foo>")
Traceback (most recent call last):
  ...
genshi.template.base.TemplateSyntaxError: invalid syntax (None, line 2)

This exception is present in 0.4.1 as well as SVN head. It seems to me that whitespace at the end of a python PI should be permitted, since it seems typical to indent the block. For example:

<foo>
    <?python
        bar = 42
    ?>
</foo>

I threw an rstrip in the PI parsing code: all tests pass (Python 2.4), as well as my above snippet. Patch against SVN head attached.

Trivial patch to rstrip source code in a <?python?> code block

Patch applied in [624], ported to 0.4.x in [625]. Many thanks!
