If you defined your root URL as your URL, then nothing. Take the
Subclipse repository as an example. The root URL is:

http://subclipse.tigris.org/svn/subclipse

When defining the connection in Subclipse, that is the URL I would
typically enter. However, many people like to enter the URL to a specific
project in the repository. If you have a big repository, like the Apache
repository, this can really save performance. So if I only wanted to work
on Subclipse, I might enter the URL as:

http://subclipse.tigris.org/svn/subclipse/trunk/subclipse

In which case, the root URL is still the previous value.

We use the root URL in this log function because it will always give us
the changed paths for a revision. For example, this command will always
work:

svn log -rXXX http://subclipse.tigris.org/svn/subclipse

But this command will fail if the path specified by the URL did not exist
at revision XXX.

svn log -rXXX
http://subclipse.tigris.org/svn/subclipse/branches/subclipse-3/core

We also use the root URL for a few other things such as calculating the
url_short decorator.
