[PATCH] Force "hg clone" to always create a new directory
From: Bryan O'Sullivan <bos@serpentine.com>
I just screwed myself by typing "hg clone foo" without specifying a
destination directory, and after I was done mopping up the mess,
concluded that this is a dangerous mode of operation that has no
practical value.
I've thus modified the clone command so that it always creates a
destination directory. If none is specified, the destination is taken
as the basename of the source.
hg clone foo
-> error, because foo already exists
hg clone http://www.selenic.com/hg
-> new repo, named hg
hg clone ../bar
-> new repo, named bar
