missing trailing spaces in some "_prepend" expressions in oe-core

["Robert P. J. Day" <rpjday@crashcourse.ca>]

  after running across a variable "_prepend" assignment that had no
trailing space, i did a quick grep through oe-core and ran across the
following, which would all seem to need that trailing space:

$ grep -rn "DEPENDS_prepend.*[^ ]\"$" *
meta/classes/qt4e.bbclass:2:DEPENDS_prepend = "${QT4EDEPENDS}"
meta/classes/cpan_build.bbclass:27:DEPENDS_prepend = "${@cpan_build_dep_prepend(d)}"
meta/classes/autotools.bbclass:24:DEPENDS_prepend = "${@autotools_dep_prepend(d)}"
meta/classes/qt4x11.bbclass:2:DEPENDS_prepend = "${QT4DEPENDS}"
$

and

$ grep -rn "SRC_URI_prepend.*[^ ]\"$" *
meta/recipes-devtools/qemu/qemu_git.bb:10:SRC_URI_prepend = "git://git.qemu.org/qemu.git"
meta/recipes-devtools/qemu/qemu_2.2.0.bb:10:SRC_URI_prepend = "http://wiki.qemu-project.org/download/${BP}.tar.bz2"
$

  there may be more, i just left it at that, not sure if there's
something magic about those examples or whether they really should
have the space added, so i'll leave it with someone else to tweak.

p.s. is there any difference between appending or prepending to the
list of build-time dependencies in "DEPENDS"? most extensions to
"DEPENDS" i've seen use "_append", but occasionally, i see "_prepend".
does it matter?
