Subject: gui: Make _gsu_node_name_pattern private.
X-Git-Url: http://git.tue.mpg.de/?a=commitdiff_plain;h=ce3fe9aefcd3c79fe87085e62684fa7d2d9bb9f2;p=gsu.git

gui: Make _gsu_node_name_pattern private.

Conform to the convention that the name of a private variables should
start with an underscore character. Also there is no need to export
the variable.
