maildirmake hangs if invoked with -q on non-existing maildir

Hi,

This is a minor bug report but an reasonable one to be fixed.

As reported originally by Alexander Koch in 2003:
 https://bugs.debian.org/214911
 https://bugs.debian.org/501557 (Duplicate)

| Following typescript shows a minor bug in maildirmake. When trying to
| create a new maildir with quota, maildirmake hangs without error
| message. Creating without quota and establishing the quota immediately
| afterwards works fine.
| 
| root@pop3:~# maildirmake -q 1000S test
| ^C
| root@pop3:~# ls -l 
| total 0
| root@pop3:~# 
| root@pop3:~# maildirmake test
| root@pop3:~# ls -l
| total 4
| drwx------    5 root     root         4096 Oct  9 12:37 test
| root@pop3:~# 
| root@pop3:~# maildirmake -q 1000S test
| root@pop3:~# 

It's annoying since it hangs without any error message.

I checked this issue with the latest maildrop 2.9.3 package, this is
true.  Checking the current source tree, "maildirmake -q 1000S test" is
not checking the existence of maildir and doing the same as
"maildirquota  -q 1000S test"... No wonder.

Why not check the existence of the maildir first and if it doesn't
exist, let's create it before setting the quota.

Regards,

Osamu
