24.2.1; sh-mode parsing - bitwise leftshift misinterpreted as here-document inside arithmetic expansion $(( )) |

The following, in a sh-mode buffer of shell-type bash:
echo -n $(( 5 << 2 ))
Will result in the remainder of the document being mis-interpreted as a
here-document and mis-highlighted until a line containing a single 2 is
encountered.
The equivalent:
let "r = 5 << 2"
echo -n $r
Is handled properly.

I've just installed a change which seems to fix this problem.
