d6bb8fc0d8 Error on backslash in comment #2132 
- Report error in case of a backspace in a comment

Backspaces in comments are no good. In most cases they are the result of
commenting out a longer line, that was broken down. This usually results
in the shell treating the following lines as their own commands on their
own lines instead of as parts of the longer, broken down line.

8bb5e01401 Allow env to have flags and variables in shebang 
The `env` command has a `-S,--split-string` option which enables
having arguments for the command in a shebang.

Also, one could use variable assignments for the command since
`env` treats only the first word without a `=` character as the
command to run.

Fixes #2143.

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'.
