This is a bug report for perl from perlbug@plan9.de,
generated with the help of perlbug 1.39 running under perl 5.12.4.


-----------------------------------------------------------------
[Please describe your issue here]

The manpage of File::Glob as an example of bsd_glob with one argument
only, but doesn't document it's semantics (at leats after multiple
readings I wouldn't see any explanation).

Naively, one would (hopefully :) assume the behaviour with no flags
specified would be like the behaviour of, well, no flags specified ("0"),
but that is not so, the default apparently includes at least GLOB_NOCHECK,
which is quite unexpected, IMHO.

It would be nice if the manpage either documented the behaviour of
"bsd_glob $scalar", or always uses an explicit flags argument.

[Please do not change anything below this line]
