Another bug I received in the debian BTS a while ago. I'm really unsure
about what to do here.
I proposed moving the "-E" option to QUILT_PATCH_OPTS a few months ago:
http://lists.gnu.org/archive/html/quilt-dev/2005-08/msg00007.html
In the ensuing discussion, I found that I couldn't get diff to generate
output that represents adding an empty file, though this should
theoretically be possible. More importantly, if I generated a
reasonable representation directly (bypassing diff), patch wouldn't
accept it and create a file.
So, in practice quilt has more problems with handling empty files than
just how the "patch -E" option is handled.
Thanks for any advice,

Quilt currently appears to unconditionally insert -E as a patch
argument (see /usr/share/quilt/patch). This causes it to remove files
that end up with a size of 0 after patching.
The patch manpage suggests that -E isn't normally necessary, and it
can cause trouble.
For example, after updating all of the autofiles for emacs21,
aclocal.m4 will have been reduced to a size of 0, but it still exists,
and the emacs Makefile depends on it existing. If the resulting
autofiles diff is represented as a quilt patch, then when it is
applied, aclocal.m4 will be removed (rather than left with a size of
0), and the emacs build will fail.
There may be some reason that quilt depends on this behavior, but if
not, it would be nice if there were some option to control the use of
-E when calling patch. It would be ideal (though perhaps not
feasible), if the use of -E could be specified per-patch, as with -p,
but a global control, or additional argument to quilt push, would be
sufficient.
Also, I listed this bug at normal severity because I wasn't sure
that it wasn't a real bug, but it might also just rate wishlist.
Thanks
