Bugzilla shouldn't mangle patches

[Jonathan Wakely]

I wanted to download my patch in comment 15 of http://gcc.gnu.org/PR2972#c15

So I clicked on the attachment link, and I get the patch viewer,
showing me a coloured, side-by-side diff.  Very pretty, but no use if
I want to download it to apply it to the GCC source.

So I clicked on the "Raw Unified" link above the side-by-side view.
That doesn't give me the original patch, it gives me some mangled
version.  The original had these headers:

--- c-family/c.opt.orig 2010-11-10 23:23:15.000000000 +0000
+++ c-family/c.opt      2010-12-03 17:08:06.932923281 +0000

But the text I get from the "Raw Unified" link has this header:

--- c-family/c.opt.orig 2010-11-10 23:23:15.000000000 +0000
+++ c-family/c.opt.orig 2010-12-03 17:08:06.932923281 +0000

Notice how both filenames now have the .orig suffix, which means the
patch won't apply to the GCC source because that file doesn't exist.

Why can't I just download my patch, in the same form I uploaded it?

I uploaded a working patch, why does Bugzilla think I need its help to
improve it?

I can go to the [details] link and copy and paste the patch, but I'm
not sure if that would correctly preserve tabs in the source, and it
shouldn't be necessary anyway.
