[yocto] SRC_URI and appending and a "style guide"?

[Robert P. J. Day]

  it's a pedantry-laden day today so i'm going to continue to whine
about aesthetics.  what about a yocto style guide for coding style
recommendations?  for example, consider the variations:

poky/meta/recipes-support/libcroco/libcroco_0.6.3.bb:SRC_URI_append = " file://croco.patch;apply=yes \
poky/meta/recipes-support/attr/ea-acl.inc:SRC_URI += "file://relative-libdir.patch;striplevel=0 \
poky/meta/recipes-support/db/db_5.3.15.bb:SRC_URI += "file://arm-thumb-mutex_db5.patch;patchdir=.."
poky/meta/recipes-sato/leafpad/leafpad_0.8.18.1.bb:SRC_URI_append_poky = " file://owl-menu.patch;apply=yes "
poky/meta/recipes-sato/puzzles/oh-puzzles_git.bb:SRC_URI_append_poky = " file://oh-puzzles-owl-menu.patch;striplevel=0 "

  in the above, you have three different variations for appending to
SRC_URI.  i don't think it would be clear to a reader if there was any
difference between "+=" and "_append", other than that "_append"
forces you to add the space yourself while "+=" doesn't.  of course,
"_append_poky" is self-explanatory.

  so is there a *preferred* form for things like that?  is it written
down somewhere?  should it be?  just because it works for perl doesn't
always mean that "there's more than one way to do it" is a good idea.
