bug#47408: Etags support for Mercury [v0.5]

There is something to be fixed if this is the expected output, as ctags invocation dose not work for Mercury files. I have not looked into the issue yet but the fix should be quite small.

What do we lose if we make Mercury support active in ctags mode?  Do
we even need to add any code for that?
