Sorry to disturb again, but it didn't work because Emacs treats
numbers as words, so the regexp \B-\B means that negative integers
like -1 get a dash instead of a minus.  And negative integers are
frequent in Python.

Is it possible to substitute *all* "-", except those in comments and
string literals?  The documentation of font-lock-mode just says that
add-keywords really works also in comments but I didn't understand
enough of it to prevent it.

Tschö,
Torsten.
