OK, I'll do a little thinking about that.

Yeah. In fact I want to do that to detect whether the convert.exe in
the path is the ImageMagick's or Windows' one (alternatively, I'm
thinking of temporarily removing %windir%/* directories from exec-path
before trying to find convert.exe).

Ah, OK. 

I have a few fixes for thumbs.el (with my latest patches it could fail
to create a valid temporary file name if thumbs-thumbdir or
thumbs-temp-dir do not end in slash), but I'll wait till I've given
