Trailing whitespace and no newline fix

If a patch adds a new line to the end of a file and this line ends with
one trailing whitespace character and has no newline, then
'--whitespace=fix' currently does not remove that trailing whitespace.

This patch fixes this by removing the check for trailing whitespace at
the end of the line at a hardcoded offset which does not take the
eventual absence of newline into account.
