In metered music, you can have a barline in the middle of a bar (e.g. a thin 
double barline, or a repeat barline). This does not affect the way 
accidentals are typeset.

If you want barlines the way you describe, then you probably don't have 
unmetered music, but just irregularly metered music. You will probably want 
bar numbers to increase between bars. The only way I can find to do this, is 
to set measureLength individually for each bar, see
5.3.9 Time administration

I think it could be nice to add a command like \newBar to lilypond, which 
would be roughly equivalent to setting measureTiming to measureLength (except 
that this doesn't work). This command should IMHO also be added to 
\cadenzaOff. (i.e., after a cadenza is over, a new bar will start). Any 
opinions?
