Thanks for clarifying the parameter space.
For my purposes either of the first 2 options would work, but my only use of
DEBUGhas been to muck with terminal state this way, so possibly users of DEBUG
withless-visible side-effects would prefer it to stay as-is. Not sure if such
usages exist orhow to trade-off the use-cases against each other.

Of course, an alternative approach would be to enhance bash with a
nativefacility for coloring emitted command-lines, to obviate the need for DEBUG
in this context.
