I'm seeing this issue with a version of Vim 7.3 proper (checked out and
compiled on or around August 21), which, if I understand correctly,
should have the fix to which you refer. I looked at your test file and
verified that I don't see the issue you reported; however, you can
reproduce my issue with your test file, simply by adding the cchar
argument to your concealends region definition (e.g., cchar=-), then
using your > map to increase conceallevel from 1 to 2. When you do this,
I believe you will find that the cchar at the start of the region
disappears, whereas the one at the end of the region remains.

It is as though the fix was implemented only for conceallevel=1...
