[Bug libc/10278] New: glob() gives inconsistent results with trailing "/"

[psmith at gnu dot org]

The POSIX spec doesn't specify exactly what should happen with a pattern ending
in "/"; all it says about slashes in patterns is:

The slash character in a pathname shall be explicitly matched by using one or
more slashes in the pattern; it shall neither be matched by the asterisk or
question-mark special characters nor by a bracket expression.

All shells I'm aware of interpret this to mean that if your glob expression ends
with a "/", it should match only directories.  GNU glob() handles this correctly
for simple globbing expressions like "*/", but for other expressions like
"dir/*/", "/*/", etc. it returns all directories with a trailing slash, AND all
files without a trailing slash.

I believe this inconsistent behavior is a bug.
