Thank you very much for this, this solution applies to all key changes
in the score, but I found it was easy to insert the code before
specific key changes and then use \revert to go back to the normal
behavior which covers that case too.
However, there is a further case where, for example, there are first
and second time bars, with the first time bar is going back to the
beginning in a different key, while the second time bar goes on in the
same key. This really requires drawing a keychange which is purely
graphical, as putting a (cautionary) keychange at the end of the first
time bar fools LilyPond into thinking the second time bar is in that
key.
This is illustrated by this example:

Is it possible to create an keychange engraver that doesn't actually
change the key, but still uses the same stencil?
