Seriously, this removes a warning when the 'list' command was invoked
(either by -L or -c list) and penv could not change to its envdir.
This is especially useful if penv is used as a make(1) environment
processor, as described in my message to -arch today. The previous
versions would complain loudly about nonexistent envdirs for e.g. all
the build, lib and run dependencies.
Happy holidays!

Long disregarded by: myself, as merely an annoyance, before
the actual development of the make(1) envproc code,
when it became a *big* noisy annoyance :)
