winelauncher patch

[Jeremy White]

Ove,

I have in fact determined why I did not use which:
On Suse (and Caldera, I believe), 
which /usr/bin/wine returns an error string,
making the whole script go straight down the drain.

What was wrong with the previous implemenation?
Are you getting a $0 value that doesn't include
the path?  In all of the test cases I have,
invoking wine seems to bring in a $0 that includes
enough of the path for the find logic to work.
