[PATCH] kernel-doc: fix some odd spacing issues 

- in man and text mode output, if the function return type is empty (like it
  is for macros), don't print the return type and a following space; this
  fixes an output malalignment;

- in the function short description, strip leading, trailing, and multiple
  embedded spaces (to one space); this makes function name/description output
  spacing consistent;

- fix a comment typo;
