Steps to reproduce

I tried this on OS X

• Set powershell as your default shell (so it doesn't inherit your default shell env variables)
• Run

> $env:PATH
/usr/bin:/bin

It doesn't have /usr/local/bin in PATH
So I cannot run powershell (and gitk, which really was my motivation)

Expected behavior

/usr/local/bin should be there
powershell should be able to run apps from it, i.e. gitk, powershell

Actual behavior

Cannot run powershell

Environment data
