Re: Jumping to C source from *Help*

      What I need to change (in order to fix umpteen bugs that
    only show up in setups such as mine) is that switch-to-buffer doesn't
    signal an error but does something else instead.

If the "something else instead" is switching to another existing
window, I feel this is contradictory to the purpose of
switch-to-buffer.  But I don't see how you could make the change you
want and avoid sometimes switching to another existing window.
