Subject: bug#21671: [PATCH] fix python.el hanging up during fontification #21657
Date: Mon, 12 Oct 2015 14:48:50 +0300

[Message part 1 (text/plain, inline)]

Two patches are included.

One fixes the fact that for some reason syntax-propertize--done has
ceased to be buffer-local after commit [1] and for some reason commit
[2] did not help. I did it the way other buffer-local variables are
initialized and it worked. The change fixes #21657 that was failing
because syntax-propertize--done was inherited from scratch buffer and
docstring boundaries were not propertized as a result.

The other infinite loop I found accidentally when adding a whitespace
before module docstring. I have fixed one corner-case of it, but in
other circumstances I'd argue that whatever smart extensions
python-mode adds to forward-sexp, those extensions should never move
point less than the normal forward-sexp should.

Cheers,
immerrr
