// Try to parse |option| as a command-line help option, which can be "-help"
// or "-help-<option>" or "-help-<topic>". The following cases are possible:
// - |option| is not '-help' nor starts with '-help-', the function returns -1.
// - |option| is '-help-<unknown>' where <unknown> is an unknown option or
//   help topic. The function prints an error message to stderr and returns
//   an exit status of 1.
// - otherwise, it prints the help to stdout and returns an exit status of 0.
