The two patches would constitute a "series".  If applied in order they
should not cause conflicts.  What I would do in this situation is make
the first one do the cleanup because that should be uncontroversial
(if it's correct and causes no user-visible change) and make the
second do the wording change.  Then Martin could easily apply the
first and ignore the second.

Many editors can highlight whitespace errors for you.  I have the
following in my .vimrc:

  " Show trailing whitespace and spaces before tabs
  hi link localWhitespaceError Error
  au Syntax * syn match localWhitespaceError /\(\zs\%#\|\s\)\+$/ display
  au Syntax * syn match localWhitespaceError / \+\ze\t/ display

But in general you should look through the diff and make sure it
includes only the changes you intend.
