I also tested it on Linux and Cygwin. See comments below.

There's a better way to do that (the way the shell script uses and you
seemingly missed in your conversion to python), i.e. using the same script
whatever the LyX version.

I have no strong feelings, but lyxeditor was historically used and there
already are other programs doing the same thing and having lyxeditor in
their name...

This is not needed when using globbing (see the revised script attached
here). Essentially, we look for ${LYXBASEDIR}* and thus catch all possible
version suffixes.

Here you forgot the separator: HOME + "/" + line[2:]

LYXBASEDIR = "LyX"

Because a pipe is not a regular file on *nix and the check would fail.

I couldn't make this to work and replaced it with
cygpath = os.popen("cygpath -a \"" + file + "\"")
file = cygpath.read().strip()
cygpath.close()
These were the most important things. For other marginal details see the
attached. The script works on both Windows and Linux but doesn't work
on Cygwin :( I don't know why.
