Frankly, I initially dismissed this issue, since I was sure bash exported
SHELL to be /bin/bash when run. However, now I see that this only happens
if SHELL was not previously set.
IMO, it's up to the individual user preference whether they want SHELL
replaced by the currently running shell, or whether they want full control
over what the value of $SHELL is. For most users, however, it would
probably be better if the shell is set to something Cygwin-ish when under
Cygwin. Maybe the default /etc/profile should contain a line setting
SHELL that power users can then comment out?
