  admitting my ignorance of the mechanics of "_append", what would it
then mean to do:

BLAH_append = "spanner"
... snip ...
BLAH_append = "toolbox"

if, say, someone does that accidentally?  and at this point, i will
leave this in the hands of people much smarter than me and move on.

  it may very well be that all of the oddities i ran across are
technically valid but, for the sake of someone perusing the source,
they should probably be cleaned up to prevent confusion.
