Errors in examples

[Phil Holmes]

In the source for http://lilypond.org/ly-examples/tab-example.png I get the 
following compile errors:

tab-example.ly:43:26: warning: ignoring too many clashing note columns
 < gis\4 d'\3 fis\2 >2 <
                         b'\2\harmonic e\harmonic >2\fermata
tab-example.ly:43:4: warning: ignoring too many clashing note columns
 <
   gis\4 d'\3 fis\2 >2 < b'\2\harmonic e\harmonic >2\fermata
tab-example.ly:42:22: warning: ignoring too many clashing note columns
 s4. < d'\3 g\2 >8 <
                     gis,\4  d'\3 fis\2 >2\arpeggio ~

Seems to me these really ought to compile clean?
