config: use the same hgrc for a cloned repo as for an uninitted repo
This just copies the same local sample hgrc, except it sets the
default path to the repo it was cloned from.
This is cut-and-paste from the local sample hgrc, but I think it's
acceptable, since the two pieces of code are right next to each other
and they're small. There is danger of them going out of synch, but it
would complicate the code too much to get rid of this C&P.
I also add ui as an import to hg.py, but with demandimport, this
should not be a noticeable performance hit.

$ hg init
$ echo a > a
$ hg ci -Ama
adding a
$ echo b > b
$ hg branch b
marked working directory as branch b
(branches are permanent and global, did you want a bookmark?)
$ hg ci -Amb
adding b
$ hg co -C 0
0 files updated, 0 files merged, 1 files removed, 0 files unresolved
Fast-forward:
$ hg merge b
1 files updated, 0 files merged, 0 files removed, 0 files unresolved
(branch merge, don't forget to commit)
$ hg ci -Ammerge
Bogus fast-forward should fail:
$ hg merge b
abort: merging with a working directory ancestor has no effect
