user-manual: more explanation of push and pull usage

Browse Source 
Recently a user on the mailing list complained that they'd read the
manual but couldn't figure out how to keep a couple private repositories
in sync.  They'd tried using push, and were surprised by the effect.

Add a little text in an attempt to make it clear that:
	- Pushing to a branch that is checked out will have odd results.
	- It's OK to synchronize just using pull if that's simpler.

For projects with few developers, or for synchronizing a few private
repositories, this may be all you need.
However, the more common way to do this is to maintain a separate public
repository (usually on a different host) for others to pull changes
from. This is usually more convenient, and allows you to cleanly

Note that the target of a "push" is normally a
<<def_bare_repository,bare>> repository. You can also push to a
repository that has a checked-out working tree, but the working tree
will not be updated by the push. This may lead to unexpected results if
the branch you push to is the currently checked-out branch!
As with git-fetch, you may also set up configuration options to
save typing; so, for example, after
