PATH: EQUAL completion fixe

[Alexandre Duret-Lutz <duret_g@xxxxxxxx>]

There was a bug in _arguments completion for `=' options :

% a2ps --prologue<TAB>
prologue
bold     bw       color    diff     gray     gray2    matrix 
% a2ps --prologue<TAB>
% a2ps --prologuebold

Since `--prologue' is recognized as an option name by ca_get_opt(), 
no `=' is added, and match are appended right after the option.

The patch below prevent EQUAL options from beeing recognized unless
there is the `=' or a space before the next word.

% a2ps --prologue<TAB>

should complete to

% a2ps --prologue=
