Bug#749175: [patch] syntax/python.vim: Fix highlight for some \N{...} sequences

[James McCoy]

Hi Neil,

The attached patch, from Jakub Wilk, corrects highlighting of \N{...}
sequences that contain numbers or hyphens (e.g., \N{HYPHEN-MINUS}).
Please consider applying and sending an updated syntax file to Bram.

Cheers,
