[wish] Remove \skip duration in Lyrics

[Abraham Lee]

All,

I've seen lately a handful of users using (and suggesting to others) the
single underscore "_" syntax to skip syllables in lyrics instead of "\skip
X", which I think is a mistake when it's obvious they did not intend to
make a melisma. It works, except the lyrics get left-aligned to the first
note.

I am wondering if anyone has a better suggestion for a pure skipped
syllable to replace "\skip X" since the duration "X" doesn't matter at all.
It's easy enough to create a replacement macro like:

space = { \skip 4 }

or something like that. I was just thinking about a complimentary syntax to
the usual spacer note "s" when inputting notes.

I'm not sure what the magic word might be, but hopefully something as
simple, or simpler, than \skip would be handy so users don't have to put a
duration after it.

OR, it could use the number to say *how many syllables to skip* instead of
a duration. I'm thinking about the instances where I've seen (and used)
something like:

skipFour = \repeat unfold 4 { \skip 4 }

What do you all think?
