OK, I see. And I do export SHELL in my bash startup scripts, so I don't have
this problem.
I can see two possible solutions:
(1) Tell users to export SHELL=/bin/bash if that's what they want processes
spawned by the shell to use.
(2) Add 'shell /bin/bash' into /etc/screenrc, on the theory that this should be
the default since bash is the default shell for Cygwin. Users who wanted to use
a different shell could override it in their .screenrc files.
Any thoughts on which is the better solution?
