bug#50852: [PATCH] Fix search of the look program.

[André A . Gomes]

Hi Emacs,

Here's a more robust way to handle the existence of the look program by
ispell.  GNU Guix users will be happy.

There's another aspect worth discussing.  The look program doesn't have
the -r flag (as of today), but ispell handles this case (look at
ispell-look-options).  It seems that look was published around 1979.
Perhaps it's time to deprecate this flag?

Thank you.
