Remove incorrect otherwise
...
You're supposed to use otherwise where you need a Boolean, not a pattern
match. This is misleadingly shadowing the real otherwise. Use _ instead.

Track whether braces were present in T_DollarBraced
...
References of the form $var and ${var} both map to the same structure in
the AST, which prevents any later analysis functions from distinguishing
them. In preparation for adding checks that need this info, add a Bool
to T_DollarBraced that tracks whether the braces were seen at parsing
time and update all references so that this change is a no-op.

Check set flags under dash & POSIX sh ( fixes #990 )
...
The set builtin accepts certain flags, and some longer synonyms (for
instance set -e is the same as set -o errexit) under POSIX sh. This
makes ShellCheck warn if any of the used flags and options are
undefined when targeting POSIX sh.
This fixes #990 , while adding general flag-support checking for set in
the process.

Check hash flags under dash and POSIX sh
...
Flags for the hash builtin other than [-r] are undefined under POSIX sh.
Dash also accepts [-v], while bash adds [-l] [-p filename] [-dt] aside
from [-r].

Issue 1330 unsupported echo flags
...
Issue https://github.com/koalaman/shellcheck/issues/1330
Addresses false positives when quoted arguments to echo begin with what
looks like a flag. Now, warn only when the first argument is a
recognized echo flag when flags are unsupported.

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.

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.
