[Freeciv-Dev] A minor style issue.

[Gregory Berkolaiko <Gregory.Berkolaiko@xxxxxxxxxxxx>]

Our coding style guideline gives conflicting signal wrt use of
spaces between "if" and the condition:

if(ptr == NULL)

vs.

if (ptr == NULL)

There are a couple of relevant bits of CodingStyle:

==========
    - spaces are inserted before and after operators ("int i, j, k;"
      instead of "int a,b,c;" and "if (foo <= bar) c = a + b;" instead
      of "if(foo<=bar) c=a+b;")
==========

and

==========
- Comments in conditionals. If you need a comment to show program flow,
  it should be below the if or else:

  if(is_barbarian(pplayer)) {
    x++;
==========

Should we clearly inforce one or the other?
