I don't think ``selected'' is more accurate or more clear in this
context than ``current''.

The latest version of the manual has this clarification:

  The specified location is actually reached only if it is in the
  current frame.

I'd suggest to craft a simple test case with inlined function and ask
the question on the GDB mailing list.  I'd expect `until' to stop in
an inlined function; the fact that the manual doesn't say anything
about this might just be a documentation bug.
