127,Strip whitespace at the end of <?python ?> blocks,Dale Sedivec <dale-keyword-genshi.e8bcba@…>,cmlenz,"A line containing nothing but whitespace at the end of a `<?python>` PI raises a syntax error:

{{{
#!python
>>> 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:

{{{
#!xml
<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.",defect,closed,minor,0.4.2,Parsing,0.4,fixed,python processing instruction pi code block space whitespace,
