[PATCH] git-remote-mediawiki: escape double quotes and LF in file names

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



A mediawiki page can contain, and even start with a " character, we have
to escape it when generating the fast-export stream. While we're there,
also escape newlines, but I don't think we can get them from MediaWiki
pages.
