#395 Wrong syntax highlighting if '<<' is in bash script

[Manfred Kreisl]

Wrong syntax highlighting when editing this bash script

#!/bin/bash
while test $(( << $(($class)) )) -le $(($nr>>1)); do
    class=$(($class+1))
done
 bla=$(($nr - $(( 1 << $(($class)) )) ))
 test "$bla" -eq '0' && echo $(($class+1)) || rec "$bla" 

joe can not deal with '<<', '>>' is working though.

FYI: jupp editor displays it correct

https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=698077 is related.

sh.jsf just doesn't handle $(…), $((…)) etc. well, and there's at least one off-by-one colouring bug which doesn't show up with default colours. The other fun bit there is that the 'here' doc which would otherwise be introduced by that<< is handled correctly…

There are related problems too with [ … ] and [[…]].
