Thanks for nice explanation. I was imagining the algorithm (slightly
different):
- find the object, which was on path "https:\\...\branch10" in
revision 11893
- backtrack the object to the right revision (the -r rev)
- checkout object which was backtracked
which somehow brought me to the idea, that -r rev is here necesary, even if
it has the same value as @rev.
So i will stick to Yours explanation wich is apparantly more correct :)

I tried this for both my branches:
svn log -q -r1:HEAD --limit 1 https:\\...\branch10
svn log -q -r1:HEAD --limit 1 https:\\...\branch7
and for both of them I get revision: r69
Indeed both branches have the common ancester.

For both the branches the revision is older.
So, If I get it right, the "expected" behaviour in this case is: there is
checkouted
object found in the 'line of history'
(in my case of https:\\...\branch7 the object was in r11893 in ancestor
branch).
This is great, because this was excpected also by me :)
There is one remaining question: Why is this not working for the second
branch:
https:\\...\branch10 (error E195012 occures).
Maybe there could arise some other complications about which I dont know ...
Nevertheless I am glad to know about the expected behavior.
Tom
