It would certainly be appropriate to file this as a bug report, but please
create a tiny example to do so.

No.  Notes are spaced according to the music layout, and chord names are
attached to the notes.  You can adjust the spacing between notes, e.g. with
an override to the 'base-shortest-duration property.  Horizontal spacing is
discussed in section 4.5 of the Notation Reference.

In my opinion, the best way to avoid chord name collisions would be to
change their vertical position, rather than their horizontal position.  I
think that the notes should govern the horizontal position, and should not
be adjusted for chord names.  Instead, chord names should be stacked, much
like markups are now.

As an admittedly inconvenient workaround, chord names could be attached to
notes as markups.


\version "2.15.1"
{
  {
    %\textLengthOn  % uncomment this line to get horizontal adjustment
    c'8 ^\markup{\halign #-0.8  {\score{\chords {c:maj7.13}\layout{}}}}
    a'8 ^\markup{\halign #-0.8 {\score{\chords {f2:13/g}\layout{}}}}
  }
}


Doing this in a music function requires advanced programming that I haven't
worked out yet.

HTH,
