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?
