I spotted this howler just below your change. (Plural noun as subject, with "is altered" as the verb.) Any chance of fixing this too? (If you don't like my wording, at least change the "is" to "are"). Cheers, Ian https://codereview.appspot.com/9116043/diff/1/input/regression/stencil-hackin... File input/regression/stencil-hacking.ly (right): https://codereview.appspot.com/9116043/diff/1/input/regression/stencil-hackin... input/regression/stencil-hacking.ly:24: GROB. The dimensions of the stencil is not affected. "GROB. It does not affect the dimensions of the stencil"
Use Ian's grammar fix and a few symbolic constants
