unable to use ( or ) when calling powershell

[hahn-kev]

Simple task defined like this:

cmd: powershell if (test-path {{.HG_REPO_DIR}}/sena-4) { rm -r {{.HG_REPO_DIR}}/sena-4 }

however when I try to run it I get this error:

task: Failed to run task "setup-win": 1:15: a command can only contain words and redirects; encountered (

So I tried various ways of escaping the (, the last one being this:

vars: 
  TEST: "(test-path {{.HG_REPO_DIR}}/sena-4)"
cmds:
  - cmd: powershell if {{.TEST}} { rm -r {{.HG_REPO_DIR}}/sena-4 }

using task --dry shows this:

task: [setup-win] powershell if (test-path ./hgweb/repos/sena-4) { rm -r ./hgweb/repos/sena-4 }

which is exactly what I want, but then when I try to run it I get the same error again

task: [setup-win] powershell if (test-path ./hgweb/repos/sena-4) { rm -r ./hgweb/repos/sena-4 }
task: Failed to run task "setup-win": 1:15: a command can only contain words and redirects; encountered (

The only related issue I found was not helpful. It said this was an escaping issue, and ended with the user changing the syntax of their command, however I can't change the syntax powershell expects, it must be if ( test ) for an if block.
