I'm not sure that I like this as a default.  You get all manner of
lossage on Linux because of this.  I.e. [a-z] in the en_US locale
matches all characters except for capital A because of the collation
order.  And on a typical Linux system about half of the system
tools will do this.  The only reasonable option is to unset the
locale at the beginning of every script or it may malfunction in
rather odd ways w.r.t. regex's and globbing.
