Field continuation is not supported by abcjs

[sjktje]

According to the 2.1 ABC standard, a "field that is too long for one line may be continued by prefixing +: at the start of the following line." Abcjs does not seem to support this feature. I find this feature particularly useful for history fields:

X:1
T:Some tune
H:Here's the long and elaborate story of how I learnt this tune and this line
+:would indeed be very long if I couldn't use the field continuation feature 
+:of the ABC standard.
C:G
ABc def|]

I tried this in the abcjs demo editor (which seems to be version 6.2.0) by adding an H: field to the default Cooley notation:

X: 1
T: Cooley's
M: 4/4
L: 1/8
R: reel
H:Here's some info about
+:this tune.
K: Emin

This results in the following output:

That's true - it's not implemented yet. A work around is to use H: instead of the plus:

H:Here's the long and elaborate story of how I learnt this tune and this line
H:would indeed be very long if I couldn't use the field continuation feature 
H:of the ABC standard.
