Yes, I now see that it is indexed as "offset", with a link to "A.19
Available music functions", but it is not indexed as "\offset".  Other
music functions are indexed both with and without the preceding
back-slash.

I had looked for "\offset" in the section of the index for items
starting with "\" - which constitutes roughly half of the entire index.
Perhaps for consistency \offset (sic) should also be listed.
