Fixes the following errors:
 * ERROR: line over 90 characters
 * ERROR: code indent should never use tabs
 * ERROR: space prohibited after that open square bracket '['
 * ERROR: do not initialise statics to 0 or NULL
 * ERROR: "(foo*)" should be "(foo *)"

It's 80 ;), and there are a few more left in this patch.

Actually I've split fixing coding style in 2 patches: one for errors and
one for warnings. In this patch some resolve the error
"code indent should never use tabs" but if on the same line there is a
warning about line exceeding 80 characters, it will be fixed in
"Fix coding style warnings" patch.
