True. So, you're saying that 'glob:noignorecase' had no effect on
the commands executed. Then the issue that the transcript reveals
is that in Cygwin, case sensitivity only affects filename specs
if globbing is used. That may, in fact, have been covered somewhere
in the documentation. (?) The transcript makes clear the dramatic
and confusing effects this can have.
But, then, I'm *sure* I'm /more/ easily confused than you. :-|, ;-)
Just like lots of other users.
