Hi
You fall into a little trap with this use of "svn merge":
$ cd trunk
$ svn merge file:///repos/trunk file:///repos/branches/B .
This merges the changes from "current HEAD of trunk" to "current HEAD of
B" into the "HEAD of trunk", which is by definition exactly equivalent
to replacing trunk with B.
Remember, before this command "HEAD of trunk" now contains "changes made
to A", and "HEAD of B" contains "changes made to B". You need to specify
a earlier version as the left source.
Try either of these:
$ cd trunk
$ svn merge file:///repos/trunk_at_2 file:///repos/branches/B .
C filea
$ cd trunk
$ svn merge -r 2:4 file:///repos/branches/B .
C filea
This merges only the changes that happened on branch B (given that B was
born in revision 2)
Hope that helps.
