changing the head to another branch

[Urs Thuermann]

Is it possible to change which branch should be the head?

Say you have revisions 1.1, 1.2, 1.3 and then create a branch.  From
here you create revisions 1.4, 1.5, ..., say until 1.10 and 1.3.2.1,
1.3.2.2 , ...  When development on the trunk stops and the main
development is on the 1.3.2.x branch, the head of the file is still on
1.10.  This means, when you work on the 1.3.2.x branch, for every
operation the server has to compute the current revision by starting
at 1.10 then applying the diffs down to 1.3 and the applying the diffs
to the most recent revision of the 1.3.2.x branch.  I imagine this may
take considerable time if you have a large project with a couple
hundred or even more files.

So IMHO it could be nice, if one could change the head to be on the
currently most active branch.
