Hi all,

Even understanding that users would need to install GNU find & grep on
their Windows system to use the new implementations bound to A/Q in dired,
I believe that we should have the following:

- NOT bind A/Q at all if the right dependencies are not found. I tried the
A binding on Windows, it looked like it was grepping for the strings I
entered and returned an empty *xref* window. The same search on same files
worked as expected in RHEL (to be honest I love this new feature on RHEL,
and I might start using the A binding). Currently the implementation on
Windows gives an appearance that something was searched for and no results
were found. That is misleading!

- Another alternative would be (if we want to keep A/Q bindings) that a
user-error or error be thrown if the correct external dependencies are not
installed. The user should be let known that they need to install the GNU
find/grep executables for their platform in order to use those commands. In
the current implementation, the user will just assume that they searched
something and nothing got returned.

- The requirement to have find/grep installed should also go to backward
incompatible changes section in NEWS.

WDYT?
