Description
:set nomagic breaks the matching for several commands. I assume not all regular expressions in the plugin specify that they require a certain magic mode.
Example:
word word word
word word word
word word word
word word word
With magic, pressing \\w matches all words and the empty line (I'm using 'X' to mark the matches):
Xord Xord Xord
Xord Xord Xord
X
Xord Xord Xord
Xord Xord Xord
With nomagic, only the empty line is matched:
word word word
word word word
X
word word word
word word word
Regular expressions in plugins should always specify the magic mode they require: \v \m \M \V
