Indeed: Once I'm adding the cygwin bin path to my windows system
environment, it works, so this is at least a temporary workaround (on
the long run, I don't want to have the cygwin path permanently set on
this machine).

I don't think "cygwin" by itself changes the path. It certainly doesn't
change the Windows system path (as defined in the "Advanced System
Settings" for Windows).

However, when I start a bash shell, /usr/bin is part of the PATH. This
happens inside /etc/profile. But this file is not always processed; This
depends on how bash is started. You can see the detailed rules in the
bash man-page, in the section INVOCATION.

My guess is that when doing a chere -2 fish, you start via bash in a way
that /etc/profile is not read. 

As for chere -1 fish, I suspect that this will never work, unless the
user has put the Cygwin bin path into his system PATH. Maybe in this
case, chere should output a warning message.
