Well, one can reasonably expect that if hi is using non-default branch,
then the changes he makes
do not apply to default branch (I use term 'branch' in general terms,
not those specific to mercurial).
According to the description above, it seems mercurial 'branch' is
almost alias to 'tag'.
Hard to say which command should work differently (maybe not 'branch',
but 'merge'), but it is
natural to expect that if I create branch (in version control terms),
make and commit some changes,
then revert to the main branch and ask for merge, then all the changes
made on branch are put into default.
Even if internally it means just moving 'default' mark to another
changeset without true merge.
