Why aliases in help on command shown on next line?

[Alexander Belchenko]

0.16rc1
===============================================================
$ bzr up -h
usage: bzr update [DIR]
aliases:
up

Update a tree to have the latest code committed to its branch.

This will perform a merge into the working tree, and may generate
conflicts. If you have any local changes, you will still
need to commit them after the update for the update to be complete.

If you want to discard your local changes, you can just do a
'bzr revert' instead of 'bzr commit' after the update.

Options:
   -h, --help  show help message

See also: pull
================================================================

Why aliases shown on next line, not on the same where 'aliases:' prefix
is? In 0.15 and before they always shown on the same line, i.e.

$ bzr up -h
usage: bzr update [DIR]
aliases: up

Is this intended change or regression?
I'd like to see them on the same line as before.
