pub fn classify_invocation(line: &str) -> Option<Effect>Expand description
Classify a single command-line invocation (one command, no shell connectors).
Leading VAR=val env assignments and a directory path on the program are
stripped; a recognized program returns its classify_command class; an
unrecognized program returns Effect::Exec (running an unknown binary is
arbitrary code execution — fail safe). Returns None for a blank line or a
comment (#…).
