Tie minimum length

[Andrew Bernard]

The NR for 2.19.82 in section 3.2.128 'tie interface' states:

min-length
If the tie is shorter than this amount (in staff-spaces) an increasingly large length penalty is incurred.

But if I use this an error is thrown. Using minimum-length works fine.

warning: cannot find property type-check for `min-length' (backend-type?). perhaps a typing error?

warning: skipping assignment

Is this a mistake in the manual for the name?
