    Visuwesh> Can you not pass keywords as non-nil values to :query and :stop?
    Visuwesh> Something like,

    Visuwesh>     (make-process :name NAME :command COMMAND :query :yes)

Only because :yes is non-nil. Also the docstring says:

    :noquery BOOL -- When exiting Emacs, query the user if BOOL is nil and
    the process is running.  If BOOL is not given, query before exiting.

which implies you can say

    (make-process :name "foo" :noquery :stop nil)

which is not true, since :noquery is checked with `plist-get'.

Whilst weʼre at it, this is inaccurate as well:

    :stop BOOL -- BOOL must be nil.  The `:stop' key is ignored otherwise
                                     ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

since the following will error:

    (make-process :name "foo" :command "ls" :stop t)
