According to the man page there is no space in between, it should be -
Werror or even -We.

But just like for C++ code I prefer for the warning to be a warning.
:-)

Please no, I am still traumatized with our use of python -tt (that by
the way is a no-op in Python 3). :-)

Thus I intend to remove -tt from existence in our code (development).

BTW in the case that you have fixed there were several problems, \w is
just the first of them.
Actually every use of the backslash in that string was a problem (and
there are 17 in there).

And you are right, linters are very good at catching those cases (here
I get that directly indication both with emacs and kate, using
plugins).
