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.

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 .
