Problem / Steps to reproduce

Using shell: bash on windows causes Windows to search for bash.exe. If WSL is installed, C:\Windows\System32\bash.exe supersedes any other bash in PATH, such as, say, cmder's bash.

WSL bash does not inherit environment variables from the calling process as it is invoking an entirely different operating system, where as cmder bash does.

It is possible to specify the full path to bash.exe but then the shell: command becomes nonportable.

Example assumes shell path for both is valid.

    env:
      testenv: success
targets:
  default:
    all: true
tasks:
  example:
    cmd: echo got $testenv

# uncomment one or the other 
#shell: C:\cmder\vendor\git-for-windows\bin\bash.exe
shell: c:\windows\system32\bash.exe
