It doesn't execute if the last char is for example a dash ...

Try an abbrev that is "a-b" (not "a to b", the chars a, dash,
and b), the "a-b" abbrev will work as b is the last char, not
the dash this time.

(dash is "HYPHEN-MINUS" officially :))

It is easy! Try setup an abbrev that is "aaaz" to "bbbz", with
the punctuation chars it doesn't work since it doesn't
trigger, that's a bug, good work YOU for finding it! Your code
works fine with "aaaz" to "bbbz", well, details aside since
you tried to do something else.

No, you did it the right way, Emacs did it the wrong way, but
as long as we have our captain going at - I don't know how
many percent? - but surely plenty enough to fix these kind of
bugs :)
