Or, write a log message that says, "I'm merging revisions X thru Y
now.". That's what the book recommends. You just run 'svn log' the
next time you're getting ready to merge, so you know where to pick up
from.

This is one of the many problems ("the repeated merge problem") taht we
hope to solve when we implement merge tracking. The VC system should
be remembering what was merged where, rather than forcing users to keep
track manually.

By the way: the CVS style of using tags to solve the "repeated merge"
problem still works in SVN. You can create a tag of each tree you're
comparing in the merge, using whatever descriptive names you want. The
next time you come back to repeat the merging process, just compare the
last tag with some new tag.
