"Including" stdin hangs LilyPond during parsing

Hi,

### BEGIN ###

\version "2.20.0"
\include "-"

\new Staff
{
    c'4
}

### END ###

Hangs during parsing:

GNU LilyPond 2.20.0
Processing `test.ly'
Parsing...
< hangs forever >

Presumably the (spurious) filename "-" dereferences to stdin, putting Lily
in a wait state for user input that's never to come.

Seems unlikely anyone would ever type such a thing. But maybe a
special-cased check wouldn't hurt.

Trevor.
