[issue2894] updating to a descendant of the current bookmark doesn't move it

[Idan Kamara]

New submission from Idan Kamara <idankk86 at gmail.com>:

$ hg init
$ echo a >> a
$ hg ci -Aqm.
$ echo a >> a
$ hg ci -Aqm.
$ hg bookmark B
$ hg bookmark A -r 0
$ hg bookmarks
   A                         0:e8b3896ff7e8
 * B                         1:bd4a62848466
$ hg upd A
1 files updated, 0 files merged, 0 files removed, 0 files unresolved
$ hg merge B
abort: nothing to merge (use 'hg update' or check 'hg heads')

The error is expected, so the user goes ahead and does 'hg update', but A is 
still on 0, and the only option is to 'hg bookmark -f A', unless I missed 
something.

You can think of A being a 'main' bookmark, and B being a 'feature' 
bookmark. The scenario above happens when 'feature' is finished and should 
be merged into 'main'.
