As you can see in ly/gregorian.ly, these are defined as BreathingSign
grobs, so you have to use overrides for the 'thickness property of
BreathingSign.

It is.  Checking the source code history, it appears that the
'extra-X-extent and 'extra-Y-extent properties were removed from
LilyPond in 2005.  Unfortunately the grob property is still
documented, and the overrides in ly/gregorian.ly still exist.  These
overrides have no affect on the musical output.

A property that does work is 'minimum-X-extent, so I changed all
'extra-X-extent --> 'minimum-X-extent, and the attached image is the
resulting output.  I don't know if this is more optimal or not, but
there is certainly a problem here.  I'll raise this issue on
lilypond-devel.
