And on Windows, that's exactly what I use.

Yes, because I want common configuration syntax and runtime
semantics across FreeBSD, Linux, Windows, et al.  The only
semantic difference is that, on Windows, if my own association
is not found, then the Windows association will apply.  This
cannot be done in the *nix environment - at least not easily -
because there is no common association repository across the
various window managers, nor is there a startfile() type
call in the POSIX world.


This is implemented already and largely works as planned.
There are a few subtleties I want to work into the next
release, but things work as expected today...
