[E-devel] [e] Patch

[rustyBSD <rus...@gm...>]

Hi,
some trivial changes.

I.   _e_fm_op_stdin_handler is unused, so -> removed.

II.  if we cannot malloc _e_fm_op_stdin_buffer, we
     are in big shit, so nullcheck.

III. Formatting.

IV.  if argc < 4 we quit, so we don't need to check
     if argc >= 4.

V.   removed 'ret' variables. They are useless and
     they were not in old revisions.

VI.  _e_fm_op_copy_atom always returns 1, so we don't
     need to always check and return 1.

Thanks !
