Gerrit applies syntax highlighting inappropriately

Gerrit appears to attemopt to apply C/C++ syntax highlighting to other file types.

For example, see http://codereview.qt-project.org/#patch,sidebyside,13331,1,tests/auto/gui/painting/qpainter/qpainter.pro – on line 9, gerrit treats the "/" on the end of "drawEllipse/" as the beginning to a C-style comment.
