The command-safety analyzer now understands ANSI-C quoted strings instead of treating them as opaque dynamic content.

The bash command-safety analyzer that decides whether a command is safe to auto-run now understands ANSI-C quoted strings like $'...\n...' and unescapes them to their literal value, instead of treating them as opaque dynamic content.
