Invalid GAE templates generated

Problem is in change
http://github.com/webpy/webpy/commit/84205cf4a0495ec5a10cb2d6d9904262d9e7ad68

This change results in such a template:

from web.template import CompiledTemplate, ForLoop, TemplateResult

import snippets
# encoding: utf-8 
    join_ = main._join; escape_ = main._escape
def main (username):
    __lineoffset__ = -4
    loop = ForLoop()
    self = TemplateResult(); extend_ = self.extend
    extend_([u'\n'])
    extend_([u'<tr>\n'])
    extend_([u'        <td/><td colspan="2">Hello, ', escape_(username, False), u'!</td><td/>\n'])
    extend_([u'</tr>\n'])

    return self

main = CompiledTemplate(main, './templates/main.html')

# encoding: utf-8 
    join_ = time_reports_individual._join; escape_ = time_reports_individual._escape
def time_reports_individual (periods):
...

And exception:

join_ = main._join; escape_ = main._escape
^
    IndentationError: unexpected indent

Instead this should look as this IMHO:

        code = code.replace("__template__", name, 1)

        out.write(code)

        out.write('\n\n')
        out.write('%s = CompiledTemplate(%s, %s)\n\n' % (name, name, repr(path)))
        # inject "join_ = ..; escape_ = .." into the code.. 
        # That is required to make escape functionality work correctly. 
        out.write('\njoin_ = %s._join; escape_ = %s._escape\n' % (name, name))
