clone: simplifying dest repo creation
since creating a repo raises an exception if the repo already
exists, there's no need to try to create one.
add some test for repo creation when the destination exists
#!/bin/sh
mkdir test
cd test
echo foo>foo
hg init
hg addremove
hg commit -m 1
hg verify
hg serve -p 20059 -d --pid-file=hg.pid
cat hg.pid >> $DAEMON_PIDS
cd ..
http_proxy= hg clone --pull http://localhost:20059/ copy
cd copy
hg verify
hg co
cat foo
hg manifest
hg pull
