Closes Alioth #311614
Globbing might occur if $cur contains one of these globbing characters: * ? [ ]
The bug becomes apparent:
On Cygwin if the glob-string contains backslashes as well, causing a warning (Cygwin >= 1.7):
MS-DOS style path detected: ...
Preferred POSIX equivalent is: ...
CYGWIN environment variable option "nodosfilewarning" turns off this warning.
Consult the user's guide for more details about POSIX paths:

On Linux, using strace, you can see bash-completion doing an unnecessary `open' system call.
Steps to reproduce on Linux using `strace':
Environment: Linux, bash-completion-1.0
1. Start bash with bash-completion loaded and find out PID ($$):
$ echo $$
MYPID
2. In a second bash shell, `strace' the above PID:
$ strace -e trace=open -f -o strace.log -p MYPID
3. Within the first bash shell, type:
$ cur="?"; _kernel_versions
4. In the second bash shell, type ^C to quick `strace'.
5. Check `strace.log', here you can see bash accessing
something it shouldn't:
...
open(".", O_RDONLY|O_NONBLOCK|O_LARGEFILE|O_DIRECTORY|O_CLOEXEC) = 3
...
6. The above call to `open' disappears if $cur in _kernel_versions gets
quoted, and you repeat the steps above:
_kernel_versions()
{
COMPREPLY=( $( compgen -W '$( command ls /lib/modules )' -- "$cur" ) )
}
Dash (-) is replaced with underscore (_). This prevents errors when
bash-completion is loaded while `set -o posix' is active:
bash: `_mii-tool': not a valid identifier
bash: `_mii-diag': not a valid identifier
