Hi Doug,
I've had a week-end away from a keyboard to think about this. The only
reason we have to use case statements for case-insensitive variable
testing is because sh(1) doesn't offer any upper/lower case handling
parameter expansions (something like ${foo~lower} for example).
When sh(1) _does_ offer something like this, a lot more work will be
involved in using it once your proposed changes have gone in.
Therefore, I propose that we create functions isyes() and isno() to wrap
up the case-handling logic. This means we end up using
if isyes(${foo}); then
...
fi
Later, when upper/lower case handling is available, we could either
change the internals of the isyes() and isno() functions, or replace
their invocations with
case ${foo~lower} in
yes)

Ciao,
