Placing clef change *after* bar line

[lilypond]

Most times, placing a clef change before a bar line is
appropriate.  When combined with repeated sections though,
sometimes it is clearer to place a clef change after the bar
line.  I read through the LSR for everything 'clef' but didn't
find anything on this topic.

The best workaround (that I've found), while limited, involves
forcing a line break at the point of the clef change and setting
the end-of-line-invisible property.

When that's not possible or desireable, I kludged up this, but
it's a gross hack looking at the code, and the spacing isn't very
good, looking at the output.  Is there a better way to tell
lilypond to put the new clef after the barline instead of before?

Thank you!
