convert-ly and lilypond-book

[Werner LEMBERG]

In the documentation, there is an example how to convert a texinfo
file to a newer version:

  convert-ly --from=... --to=... --no-version *.itely

A similar command can be used for lilypond-book input files:

  convert-ly --from=... --to=... --no-version *.tex

What I consider problematic is that syntax changes aren't restricted to lilypond
environments.  Just consider this input:

  \version "2.11.50"

  orientation

If you say

  convert-ly --to=2.11.51 test.ly > /dev/null

You get this output:

  convert-ly (GNU LilyPond) 2.13.31
  Processing `test.ly'... 
  Applying conversion: 2.11.23, 2.11.35, 2.11.38, 2.11.46, 2.11.48, 2.11.50, 
  Not smart enough to convert orientation in fret-diagram properties. Use 
fret-diagram-details.
  2.11.51

which can be quite irritating.  Fortunately, no action is taken upon,
but this is just accidentally true.

To sum up: Keywords like `orientation' are far too frequent in normal
text to be handled without protection if convert-ly is applied to
lilypond-book (or texinfo) input.
