1. emacs -q
2. M-: (progn (switch-to-buffer-other-tab "*Messages*") (buffer-name))
- Actual result: "*GNU Emacs*" in echo area.
- Expected result: "*Messages*" in echo area.

You can work around it by calling set-buffer right after
switch-to-buffer-other-tab, but that shouldn't be necessary.  
The other switch-to-buffer-... functions all set the buffer correctly.

Can you explain why you expected to see "*Messages*" in this case?
What kind of documentation says this is what should happen?

Thanks.

All the other pop-to-* and switch-to-* functions set the buffer, and the
language "switch to buffer" in Emacs includes making the target buffer
current.

I can't see any reason why switch-to-buffer-other-tab should be
different from its fellows.

The documentation for switch-to-buffer-other-tab says that it is "Like
C-x 5 b", and switch-to-buffer-other-frame makes the target buffer
current.

Both switch-to-buffer-other-window and switch-to-buffer-other-frame
use pop-to-buffer, but it was unnecessary for switch-to-buffer-other-tab
since it sets the current buffer implicitly afterwards.
But you are right, this causes the problems on a programmatic use
of this command.  So now this is fixed in master.
