I have the following revisions in the mergeinfo between two of my branches.
sh% svn mergeinfo --show-revs merged '^/trunk' '^/branches/myotherbranch'
r139784
r139796
r139883
r139944
r139953
r139994
r140005
And I want to remove one of the revisions from this list, so that I can attempt to do the merge again. How do I go about doing this?
