px feature request: show process environment variables #116
Description
I think it would be a great feature for px to also show the target process' environment variables.
procfs provides /etc/"$SOME_PID"/environ. Executing e.g. strings /proc/"$SOME_PID"/environ or cat /proc/"$SOME_PID"/environ | tr '\000' '\n' shows process $SOME_PID's environment variables at the time that process was started.
Maybe it is even possible to additionally show process $SOME_PID's environment variables at the moment they are investigated with px (i.e., "the current environment of that process).
