Using null followed by a head, tail, or a partial pattern match is
an anti-pattern. Use case matching instead.

0e0de94045 Fix issue #1724 
(bash: missing support for 'builtin' keyword)
Now shellcheck looks for the arguments to 'builtin' to determine
read/written variables. A change in the parser makes sure that
assignments are parsed correctly in commands that start with 'builtin'.

aa3b709b5d 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.

This ensures that the parser and other places that refer to special
variables can use the same list.

af46758ff1 Add option to look for sources in alternate root paths 
Add a new optional flag "-r|--root ROOTPATHS", where ROOTPATHS is a
colon separated list of paths, that will look for external sources in
alternate roots.

This is particular useful when the run-time environment does not fully
match the development environment. The #shellcheck source=file directive
is useful, but has its limitations in certain scenarios. Also, in many
cases the directive could be removed from scripts when the root flag is
used.

Script example.bash:
  #!/bin/bash
  source /etc/foo/config

Example usage where etc/foo/config exists in skel/foo:
  # shellcheck -x -r skel/foo:skel/core example.bash

This is motivated by the fact that the popularity of bats is increasing
since the creation of bats-core/bats-core.

The code is a cherry-pick of koalaman/shellcheck/bats branch.

Fix koalaman/shellcheck#417.
