\mark\markup\left-align bug

[John Williams]

I wanted a text markup at the very beginning of the staff, instead of over
the first note.  The \mark appears there, but it is centered over the
spot.

I tried: (lilypond-2.0.1)

\mark\markup{ \left-align "Lively in the upper octave." }

But that doesn't work.  It stays centered (and extends quite far to the
left of the beginning of the staff). Is \mark ignoring it?

Also: (documentation bug)

\left-align (and others) is not documented in Tuning output -> Text
markup. It is only documented under a different name (left-align-markup)
in program-reference -> Markup functions.

And lastly:

left-align-markup in scm/new-markup.scm (lilypond-2.0.1)
is identical to right-align-markup: it says "RIGHT"!

         (ly:molecule-align-to! m X RIGHT)
