(I'm going through old bug reports that unfortunately weren't resolved
at the time.)

I vaguely remember that the LaTeX team once said that there is no
special need to use \(.\) instead of $.$ (I can't find the reference,
though), so we can presume that $.$ is used much more often.  Hence, I
don't think we will fix this inconsistency, and therefore I'm closing
this report.
