http://code.google.com/p/lilypond/issues/detail?id=2820

the dots are symmetric to the centre of the staff, so either both or none  
of them are outside.  I didn't want to special case staves of two lines,  
only to write regtests of even line staves the simplest was to use two  
lines.  I guess two-line staves looked like that in 2.14 too.
having said all that, if you think it worth doing, I'll special case  
two-line staves.

the last case of repeat-sign.ly is not simply a 0-line staff, but no staff  
- I think that's why there are no bar lines at all.  the code handles  
0-line staves, see lyrics-bar.ly.

I've added a repeat-sign-in-tablature regtest in a new file  
tablature-repeat.ly.  It may be better to be in repeat-sign.ly - what do  
others think?

the regtest framework sucks; it doesn't report all cases I expected, but  
verified manually that the patch works as intended.  (I run make  
test-baseline with the new regtests, old bar-line.scm)
