Currently, it doesn’t seem to be possible passing a `DRONE_COMMIT` variable containing a colon like `feat: foobar` since the parser tries to convert that into a map type. The same happens when trying to escape quote as `DRONE_COMMIT="\"feat: add feature\""`.

This also seem to be an issue regardless the content of `drone.yml` while using or not the `DRONE_COMMIT` variable.

See below:

```auto
$ drone -v
drone version 1.2.2

$ DRONE_COMMIT="feat - add feature" drone exec # works

$ DRONE_COMMIT="feat: add feature" drone exec
2020/10/17 09:54:22 yaml: unmarshal errors:
  line 52: cannot unmarshal !!map into string

```

Thank you I have missed the that fact there was a one occurrence of `DRONE_COMMIT` in the pipeline I hadn’t spotted previously, which was causing the issue. Sorry for the false alarm.
