I trusted xgettext documentation that says that it handles C++ input
source files. 

Looking at the documentation, I notice this:

       By  default  the  language  is guessed depending on the input
       file name extension.

I don't know whether after the switch C++ xgettext is being invoked
explicitly with -C or --c++, or whether we are still relying on xgettext
to pick the language based on the file extension.  This is probably
another reason why we might want to rename files to use apppropriate
extensions.  In the meantime, we might want to explicitly specify the
language for the input source file.

po/exgettext only looks whether the parameter name ends with 'msgid'.

Hmm, why would that be needed now, and not before?
(not that I am found of the conditional, but only by curiosity.)
