Forgive me if I'm making unjustified assumptions here as I'm only
familiar with Scottish Country Dance music and not bagpipe tunes
in general.

Normally you "pay back" the partial measure only at the end of a
piece. Where the first section is repeated, the last measure of the
section will be short, but that gets paid back immediately by the
start of the next section, which will have a matching up-beat.

So your example might look more like the attached. (I borrowed the
earlier measures to fill it out.) Excuse my changing the \bar ""
strings for 2.19.44.

I've also attached a dance tune, mangled for copyright, as a real
example. The chunks overlap.

Cheers,
David.
