man page documentation differs from actual program

[Donny Viszneki]

From these man pages:

/usr/share/man/man1/ctags-exuberant.1.gz
/usr/share/man/man1/ctags.1.gz

Excerpt:

       Note also that the boolean parameters to the long form options (those
       beginning with "--" and that take a "[=yes|no]" parameter) may be omit‐
       ted, in which case "=yes" is implied. (e.g. --sort is equivalent to
       --sort=yes). Note further that "=1" and "=on" are considered synonyms
       for "=yes", and that "=0" and "=off" are considered synonyms for "=no".

Actual behavior:

donny@pacemates:~$ ctags --sort=yes /dev/null
donny@pacemates:~$ ctags --sort /dev/null
ctags: Invalid value for "sort" option
