patch::: 1.3.48.jcn1

1.3.47.jcn3
===========

* Rewrite of chord-name production in scheme.  There are two major styles
  now, banter and american.  To get american style, use

      \property ChordNames.chordNameStyle = "american"

  Most anything should be possible now.  See input/test/american-chords.ly

* Added isinf check to configure.in, and isinf macro from guile to
  bezier.cc; solaris has no isinf ().

* Fixed star-spangled-banner with not-so-nice \bar "|." fix.  Almost
  perfect now.

* Added output property to regression test.

* Fixed warning of creating existing outdir.

* Added `Mark' interface to text-items that are marks (thanks, HW).
