Function appendShellString

src/fe_utils/string_utils.c:602–612

* Append the given string to the shell command being built in the buffer, * with shell-style quoting as needed to create exactly one argument. * * Forbid LF or CR characters, which have scant practical use beyond designing * security breaches. The Windows command shell is unusable as a conduit for * arguments containing LF or CR characters. A future major release should * reject those char

 * returns false if there were any.
