Changes to PATH do not persist

[CumpsD]

When changing the PATH variable from inside cmder, it does not get persisted to the real Windows environment variables.

I know cmder inject stuff into the PATH, wouldn't it make sense to keep track of what it injected before/after and strip that from the PATH and update the real PATH with that.

This issue is causing me to have scripts which modify the PATH to fail afterwards, since the PATH wasn't really updated, besides in that one instance

Repro:
echo %PATH%
set PATH=%PATH%;test
echo %PATH%

Close cmder
Reopen cmder

echo %PATH% -- No more test

Have you tried something like this?

    setx MY_PATH "c:\a\b\c"
    setx PATH "%PATH%;MY_PATH%"

As @hopbit pointed out set is only for local variables. So this behavior is correct.
