There were several issues related to both markups and lyrics.  Pertinent
last change would seem to be 2.17.4:

commit 38a4081efa4a8ee2f5da780ca0ed2991627afc46
Author: David Kastrup <address@hidden>
Date:   Sun Sep 30 02:21:00 2012 +0200

    Issue 2869: Regularize lyrics lexer mode
    
    That makes lyrics mode rather similar to markup mode regarding how
    words are formed.  {} are never considered part of words unless
    enclosed in quotes.  Unquoted words do not contain whitespace, braces,
    quotes, backslashes, numbers or Scheme expressions.  In addition, they
    cannot start with * . = and | since that would mess with duration,
    assignment and barcheck syntax.  This removes some remaining
    TeX-oriented cruft in the lexer.  The set of word-non-starters might
    need revisiting, but at least the regtests seem to pass.

Actually, I would have thought to have cleaned that up before 2.16 but
it appears like at least in this respect the years are passing slower
than they feel to me.

It's probably worth pointing out that the above Issue 2869 was _not_ a
longstanding issue in the tracker.  Its first appearance was immediately
accompanied with a patch.  So why would I have changed matters appearing
to new and inexperienced users' perception as "exception" when my own
perception would be a completely different one?
