Charles,
As shown below, sh.vim is too loosely interpreting the arithmetic
expansion syntax. As noted in Bash's manpage and SUS[0], arithmetic
expansion should be treated as if the contained expression were within
double quotes. shArithmetic should contain a cluster that doesn't
include shSubSh.
Also, I noticed that the default syntax highlighting highlights $(()) as
an error. Should that be the case since it is specified in SUS?

The following is highlighted badly:
start file
#!/bin/bash
echo $(( ( 2 5 ) + 1 ))
echo foo bar
end file ==
The 5 is the wrong colour and everything following until the end of file
is highlighted as if it were quoted text. Removing the parentheses around
the sub-expression corrects the highlighting but changes the meaning of the
expression.
Hello!
The was getting treated as the start of a here document -- so that
explains the treated as text problem. Please try the attached file.

handling /bin/sh with is_kornshell/is_sh {{{1
b:is_sh is set when #! /bin/sh is found;
However, it often is just a masquerade by bash (typically Linux)
or kornshell (typically workstations with Posix sh).
So, when the user sets is_bash or is_kornshell,
a b:is_sh is converted into b:is_bash/b:is_kornshell,
respectively.
