Trouble with creating a patchfile (when hitting a file with missing newline at end of file)

[Marko Käning]

Hi guys,

I am having severe trouble with a patchfile which I try to apply in the kmymoney4 port.

I created the patchfile with the command

	$ svn diff svn://anonsvn.kde.org/home/kde/tags/kmymoney/4.5.1 svn://anonsvn.kde.org/home/kde/trunk/extragear/office/kmymoney >patch.diff

OK. So far so good.

I test the patch by applying it to a local working copy being at the old revision

	$ patch -p0 <patch.diff

and it runs through without any problem.

BUT, when I try the same using my portfile's patchfiles like this 
---
.
.
.
patchfiles       patch.diff
patch.dir         ${workpath}/${distname}
patch.pre_args    -p0
.
.
.
---
I eventually end up with an error like this:
---
$ sudo port patch
.
.
.

This all seems to be caused by that the said file developer-doc/phb/CMakeLists.txt misses a newline at the end of the file, as you can see when peeking into the patchfile:

This seems to irritate the patch command.

I have no idea, though, why it works if I apply it manually, but fails when I try it using "port patch".

I am aware of that missing newlines at end of file are often a problem for patch, but I wonder what's causing this differences here.
I already wasted hours to find a solution, yesterday and today. :-(

I hope so much you guys have a hint for me.

Greets,
Marko
