... and we can do that just fine if we
* record the prior value we're over-riding on some master object,
that also remembers the list of regexes;
* call qputenv() exactly as you have in mind;
* when about to start a sub-process, ask that master object if the
command name matches one of its regexes;
* if it does, restore *for only it* (e.g. after fork()) the prior value.
The default for everything else is then to see an environment with our
"correction" applied to the locale env var(s).
