Bug Description

Loading a DTD from a path containing a space fails. E.g.:

lxml.etree.DTD( "/tmp/a b.dtd" )

will lead to:

Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "dtd.pxi", line 297, in lxml.etree.DTD.__init__ (src/lxml/lxml.etree.c:143528)
lxml.etree.DTDParseError: failed to load external entity "NULL"

Doing:
fd=open( "/tmp/a b.dtd", "r" )
lxml.etree.DTD( fd )
fd.close()

works as expected. Parsing an xml file like with lxml.etree.parse( "/tmp/a b.xml" ) works, too.

Right, only URLs are supported here. Thus, "file:///tmp/a b.dtd" works, but a plain file name does not. It should.

Funny enough, URL escaping works here, i.e.

lxml.etree.DTD( "/tmp/a%20b.dtd" )

I don't think that's generally a good thing, however unless the path really *is* a URL. People might actually have deliberately used a "%" in their file name...
