Check unset flags under dash and POSIX sh 
The only acceptable flags for the unset builtin under POSIX sh and dash
are [-fv]. Bash though, accepts [-n] too. This commits makes shellcheck
warn about this.

Check type flags under dash and POSIX sh (fixes #1471) 
There are no flags for the type builtin defined under POSIX sh, nor does
dash define any. Bash, however, allows [-aftpP]. We check this now under
POSIX and dash.

Check trap flags under dash & POSIX sh (fixes #1461) 2019-01-16 08:44:41 +01:00
Vidar Holen c6c615217b Allow specifying that flags should not be checked for support. 
This was motivated by the fact that `-a` was missing from Dash's
long list.

Consider type a valid command in sh 
[type](http://pubs.opengroup.org/onlinepubs/9699919799/utilities/type.html) *is* defined by POSIX, and even the bourne shell has the `type` command.
