missing 'which' documentation

[Lee D. Rothstein]

Does anybody know or care that there is an option --
'-a' -- for 'which' -- that is not documented on
Cygwin. That is, there is no internal help, and there
is no 'man' or 'info' page provided by Cygwin install.
If anybody wants this, I will find or create the 'man'
page and make it cover '-a', and then do *what* with
it? Pointers appreciated!

To see the value of this option try (assuming you have MS
executable directories in your path):

  which ping              vs         which -a ping
  which find              vs         which -a find

and

  which dir               ==         which -a dir

i.e., 'dir' is an internal of 'cmd.exe'
