Personally I find "(|.:)" slightly less intuitive than "(.:)?", so could
I maybe talk you into using the alternative form?

However, seeing your further reply (mainly targeted at Alan) I also
wonder whether the issue can't be addressed in a more general manner, by
pruning drive letters from diagnostics before actually doing any regexp
matching. Such pruning could then also be limited to actually running on
Windows, whereas changing expectations in test cases would affect all
targets.
