Description:
------------
The tool generates incorrect patches when patch contains lines that diff only in 
trailing spaces, for example, in this patch: https://edit.php.net/index.php?
patch=ru/features/cookies.xml&project=PHP

original line 
"когда включена директива <link linkend="ini.track-vars">track_vars</link>."
should contain trailing space, while patched line doesn't. As you can see in the 
patch lines are identical - this makes patch(1) reject these hunks.

In Expected/Actual result sections I enabled "End-of-line" mode, so it's easier 
to spot trailing spaces.

Expected result:

Comment to exec-to-passthru patch:
I've changed implementation of SaferExec::execMulti from exec() to ob_start() + 
passthru(), since exec() 
trims trailing spaces as noted in http://php.net/manual/en/function.exec.php.
