The "NOTE" issued by

   $ /bin/true --help

was one reason for me I looked into this.  I assume that for GNU
bash this note refers to bash's info pages (and not, for example, to
some POSIX spec).  (And please do not tell me that the buried note
about bash true not supporting options was sufficient here.  There
is no need to keep info pages as cryptic short as possible.)


$ /bin/true --help
Usage: /bin/true [ignored command line arguments]
  or:  /bin/true OPTION
Exit with a status code indicating success.

      --help     display this help and exit
      --version  output version information and exit

NOTE: your shell may have its own version of true, which usually supersedes
the version described here.  Please refer to your shell's documentation
for details about the options it supports.
