[Pkg-haskell-maintainers] Bug#754990: shellcheck: false positive SC2004 for $$ in (( ))

[Justin B Rye]

Package: shellcheck
Version: 0.3.3-1
Severity: normal

jbr at hurakan:~$ cat ./hellcheck
#!/bin/bash
(( $# == 666 )) && echo 'satanic number of arguments!'	# okay
(( $$ == 666 )) && echo 'satanic PID!'			# "error"

jbr at hurakan:~$ shellcheck -f gcc ./hellcheck
hellcheck:3:4: note: $ on variables in (( )) is unnecessary. [SC2004]

Thankyou for shellcheck!
