It's a *bash* default - it has nothing to do with Cygwin as distinct
from other bash installations. If you had a different experience
elsewhere, it could be that the default was overridden in some system
wide bashrc file - but that strikes me as unlikely. I suspect that
this is done as a security measure, to prevent an alias from introducing
a surprise.
