I think they could be added to ly/chord-modifiers-init.ly

I concur with the c:1.5 and c:1.5.8  I prefer these to c:5^3 and c:5^3.8

These should be added to Appendix A.2 Common chord modifiers.

Since this uses \set, it belongs in the manual in the form of a snippet.
Write the documentation right into the texidoc for the snippet, and make
sure it gets added to the LSR with a docs tag and a fretted strings tag.

Then, we'll need to modify the Selected Snippets section of NR 2.4.2 to
include your snippet.

Also, I'd recommend that we consider adding the power chords to
ly/predefined-guitar-fretboards.ly.  Currently, the manual shows how they
could be added as alternate voicings of regular major chords.  But now that
you have specific chord modifier sequences for power chords, I think it
makes great sense to add them to the predefineds.  If we do that, then we
don't need to worry about adjusting minimumFret when transposing (and the
predefined fretboard will automatically be transferred to the tablature).

Thanks,
