ref-log: style fixes.

A few style fixes to get the code in line with the rest.

 - asterisk to make a type a pointer to something goes in front
   of the variable, not at the end of the base type.
   E.g. a pointer to an integer is "int *ip", not "int* ip".

 - open parenthesis for function parameter list, unlike
   syntactic constructs, comes immediately after the function
   name.  E.g. "if (foo) bar();" not "if(foo) bar ();".

 - "else" does not come on the same line as the closing brace of
   corresponding "if".

The style is mostly a matter of personal taste, and people may
disagree, but consistency is important.
