Not quite. How many Cygwin executables with dots in the filename
(excluding the final .exe, of course) are there in the distribution?
Anyway, you _are_ right. You have the right to want to build something
like 'my.app', and then thing gets borked.
But as I said, this is just a DEMO of what's possible to do. If we
wanted to really step into this, and ensure a 100% solution, that
would involve a much more elaborated approach (i.e., involving a lot
of shell integration work).
I'm afraid the work to fill in that gap would not justify the small
gains, though.

That's what the regtool example I gave is doing, basically.

As I'm not a native speaker, I found your english truly enjoyable.
Maybe mine is as terrible as yours, but no one as told me yet! :)
