Undocumented numeric globbing flags

[Peter Stephenson <p.stephenson@xxxxxxxxxxx>]

Does anyone use the undocumented globbing flag feature that a number
with no flag is treated as a set of octal bits to "and" with the file
mode?

I only discovered this when I mistyped a set of flags that should have
contained a numeric argument and it was silently misinterpreted as
something entirely different.

As far as I can see this is completely superseded by the "f" qualifier.
