Description

For example, running the default "svn update" command would do the equivalent of:
svn merge --dry-run -r BASE:HEAD .

This of course, assumes that all files are on the same revision. Otherwise, --dry-run should work on a file 
by file basis, ie. updating file A would do this, updating file B would do that, etc.
