ly/bagpipe.ly:22: (c-flat . ,(ly:make-pitch 1 0 FLAT))
Why are you removing the definitions c-flat, f-flat, g-flat?

https://codereview.appspot.com/241270043/diff/1/ly/bagpipe.ly#newcode14
ly/bagpipe.ly:14: \version "2.19.0"
Rewind the version?  Why?  Well, it does have the advantage that the
next run of update-with-convert-ly run will remove obsolete
parser/location arguments (see later).  But it seems saner to add the
file in the proper version.

ly/bagpipe.ly:94: stemspace = #(define-music-function (parser location
extent) (pair?) #{
Please remove the parser and location arguments here.

ly/bagpipe.ly:97: pgrace = #(define-music-function (parser location
notes) (ly:music?) #{
And here.
