local::lib bootstrap no longer prints correct environment variables

[andk]

Please add a sample what you mean to be printed wrongly. What do I have to do to see this bug?

It's this line that's the problem:
https://github.com/andk/cpanpm/blob/master/lib/CPAN/FirstTime.pm#L1344

It should be giving us a list of environment variables and we're getting an
empty string instead.

To replicate, you need a to have no CPAN configuration and have a perl for
which you don't have write access. Running "cpan" the autoconfig should
ask if you want local::lib. If you say yes, at the end of the bootstrap is
says "here's what you need to put in your bashrc:" but then it shows
nothing.

I think I know what's going on here. When a local::lib directory is active (and the most recently activated), it won't re-add it to the environment variables it outputs. It also was meant to behave like that before the internals change, but my changes seem to have made it happen in more cases.

One easy fix would be to save the ->environment_vars_string_for output before setting the %ENV options. I'll probably made some changes to local::lib because of this though. Someone else at the QA hackathon requested that local::lib be less 'smart' in this regard.

Maybe it can be "optionally" smart/dumb.

I think this problem or a variation of it is back, per https://rt.cpan.org/Ticket/Display.html?id=103760
