Gerrit should not treat qfoo.mm:123 as hyperlink

See https://codereview.qt-project.org/c/qt/qtbase/+/268400 for example.

There are some comments mentioning qcocoanativeinterface.mm:62:32: error: ... which is treated as a hyperlink that leads to the qcocoanativeinterface.mm domain.

For example here: https://codereview.qt-project.org/c/qt/qtbase/+/268400/3/src/plugins/platforms/cocoa/qcocoanativeinterface.mm#62
