[MiNT] Coding style. Pre-processor directives

Hi all,

ADVISE: This is very trivial. :-)

I have seen through the kernel sources two ways to put pre-processor
directives, e.g.:

#include "xxxxx.h"
#define XXXXXX

and

# include "xxxx.h"
# define XXXXXX
(note the space between # and the first letter)

Even I've seen these two ways in the same file, e.g.:
http://sparemint.org/cgi-bin/cvsweb/freemint/sys/mint/kentry.h?rev=1.39&content-type=text/x-cvsweb-markup
http://sparemint.org/cgi-bin/cvsweb/freemint/sys/mint/lists.h?rev=1.2&content-type=text/x-cvsweb-markup

The second way (with the space) looks like is the most used.
Any reason for this? (I guess not), If not, Which one should I use?

Thanks
