man lilypond   for 2.18.2 doesn't give any indication that you can
input through stdin. You have to delve into   info lilypond   which
I tend to forget to do. (linux version)

Not here. The only difference I can see between reading from a file
and from stdin is that stdin reads only 4096 bytes at a time. This is
true even where stdin is connected to the file (ie   lilypond - < file.ly
rather than   cat file.ly | lilypond -   as above) so lilypond knows
the length of the file.
