No.  -m means to find all the names (in any hash table) that match a
pattern.  -a means to show all the occurrences in $path of each name
(either literally without -m, or found in the command hash table by
-m).  -m happens first, and then -a searches the path.

Whether a full path appears there depends on how the function was
defined.  The only way you get the output with "... from ..." but
without the full path is if you source the function from a file in the
current directory (e.g., "source rap").  Even autoloading the function
with "fpath=(.); autoload rap; rap" gets you the full path.
