Braille Output: Anacrusis (Pic-Up bar) should be labelled 0.

Issue type

Accessibility issue (e.g. for keyboard-only or screen reader users)

Description with steps to reproduce

When a score with an anacrusis is exported to Braille both the anacrusis and the first full bar are numbered in Braille as 1. The pick-up bar should be numbered 0 in Braille. If requested bar numbering is added to the Braille Live Braille View then this may effect that also.

STEPS:

1. Create a score with a pick-up bar.
2. Exclude the pick-up from the bar count so the score shows bar 2 as print bar 1.
3. Go to File Export and select Braille.
4. Notice the resulting Braille file when viewed in a Braille editor shows bar numbers down the left margin starting with 1 on the first line at the beginning of the right hand and then the numbering shows 1 again at the first full bar. The bar count is correct but the pick-up bar should be labelled as 0.
