[Zope3-checkins] CVS: Zope3/src/zope/tal - talgettext.py:1.10

[Barry Warsaw]

Update of /cvs-repository/Zope3/src/zope/tal
In directory cvs.zope.org:/tmp/cvs-serv27759/src/zope/tal

Modified Files:
	talgettext.py 
Log Message:
Teach this about the standard .pot file header so that it can add it
if it's creating the file anew, or if the file its updating doesn't
have a msgid of the empty string (the GNU gettext standard way of
marking metadata).

de-string-module-ification and boolean-imitilism.
