    Issue 3401: Parser error with void function in music list

    Problem code fixed:

    test =
       (symbol-list?))

    {
      \test Symbol
    }

    This patch is sort of a so-so fix for the problem: for one thing,
    embedded_scm_closed should not have been able to end in a symbol list
    in the first place since parsing those requires lookahead for '.'.
    The grammar has now been changed to use embedded_scm, and just backs
    up in the case a scheme function/identifier returns a markup in lyrics
    mode (which can then be assembled with duration and post-events into a
    more complex music expression).  If parsing the source for the markup
    required lookahead, the same error will be thrown.

    But that use case of Scheme functions in Lyrics mode for generating
    markups to be turned into lyric events is a lot more exotic than the
    one triggering this issue.  The current fix at least results in
    predictable behavior outside of using Lyrics mode, and in particular
    for uses of define-void-function.
