Just by way of providing an additional perspective, I thought I'd illustrate
how Mercurial handles this situation:

$ mkdir repoA
$ cd repoA
repoA$ hg init
repoA$ echo foo > foo
repoA$ hg add foo
repoA$ hg commit -m "added foo"
repoA$ cd ..
$ hg clone repoA repoB
updating working directory
1 files updated, 0 files merged, 0 files removed, 0 files unresolved
$ cd repoA
repoA$ cat >> .hg/hgrc <<EOF
> [paths]
> default = ../repoB
> EOF
repoA$ echo bar > bar
repoA$ hg add bar
repoA$ hg commit -m "added bar"
repoA$ hg push
pushing to /Users/jay/repoB
searching for changes
adding changesets
adding manifests
adding file changes
added 1 changesets with 1 changes to 1 files
repoA$ cd ../repoB
repoB$ hg parents
0   d32c3edefcba   2009-02-08 11:18 -0500   jaysoffian
  added foo

repoB$ hg glog
o  1[tip]   8e0a16e691f4   2009-02-08 11:19 -0500   jaysoffian
|    added bar
|
@  0   d32c3edefcba   2009-02-08 11:18 -0500   jaysoffian
     added foo

repoB$ echo baz > baz
repoB$ hg add baz
repoB$ hg commit -m "added baz"
created new head
repoB$ hg parents
2[tip]:0   8d7db8257fd0   2009-02-08 11:19 -0500   jaysoffian
  added baz

repoB$ hg glog
@  2[tip]:0   8d7db8257fd0   2009-02-08 11:19 -0500   jaysoffian
|    added baz
|
| o  1   8e0a16e691f4   2009-02-08 11:19 -0500   jaysoffian

o  0   d32c3edefcba   2009-02-08 11:18 -0500   jaysoffian
     added foo

Now let's look at what happens if I pull from B, instead of pushing from A:

$ rm -rf repoA repoB
$ mkdir repoA
$ cd repoA
repoA$ hg init
repoA$ echo foo > foo
repoA$ hg add foo
repoA$ hg commit -m "added foo"
repoA$ cd ..
$ hg clone repoA repoB
updating working directory
1 files updated, 0 files merged, 0 files removed, 0 files unresolved
$ cd repoA
repoA$ echo bar > bar
repoA$ hg add bar
repoA$ hg commit -m "added bar"
repoA$ cd ../repoB
repoB$ hg pull
pulling from /Users/jay/repoA
searching for changes
adding changesets
adding manifests
adding file changes
added 1 changesets with 1 changes to 1 files
(run 'hg update' to get a working copy)
callisto:~/repoB$ hg parents
0   1adbe0643fb7   2009-02-08 11:22 -0500   jaysoffian
  added foo

repoB$ hg glog

     added foo

repoB$ echo baz > baz
repoB$ hg add baz
repoB$ hg commit -m "added baz"
created new head
repoB$ hg parents
2[tip]:0   cb8f0c639bd4   2009-02-08 11:23 -0500   jaysoffian
  added baz

What I especially like about Mercurial here is that pushing from A is
perfectly symetrical to pulling from B.

With git, cloning sets things up to fetch into a tracking branch, but then the
push is not symetric to the fetch. That makes sense if you're cloning from a
bare repo, but I think leads to confusion for new users when they clone a
non-bare repo they wish to later push into. I dunno, I guess we'll see if the
new message helps any.
