That was kind of on purpose.  :-)

The best name I could think of is "scope".  If we call these things
scopes, we can also rename the itfocus command to "scope", which can
be abbreviated as "sc".  ("s" is already step, obviously).  It's spelled
itfocus currently because "focus" was already taken by the TUI.

It looks like this:

curinf> scope t3 break -stop i1 main
Breakpoint 2 at 0x40068c: file threads.c, line 35.
curinf> scope i1
Current inferior is 1.
i1> sc all
Current inferior is 1.

WDYT?

I've implemented it.  I'll post a WIP v2 series with that change (and
many others) shortly.
