[PATCH] convert.c: fix some sparse warnings

Sparse complains thus:

      SP convert.c
  convert.c:178:24: warning: Using plain integer as NULL pointer
  convert.c:239:28: warning: dubious: !x & y

Hi Torsten,

When you next re-roll your 'tb/convert-eol-autocrlf' branch, could you
please squash this into your patch corresponding to commit cbcc0471
("convert.c: more safer crlf handling with text attribute", 22-04-2016).

[No, you have seen this before! ;-) ]

Thanks!

ATB,
Ramsay Jones

Thanks,
your update has been applied and was lost later. Sorry for that.
I will send out a v7, after waiting for more comments on v6b.
