Suggest a strategy to include absolute paths

[jgillis]

If I understand correctly, the current implementation treats all paths as relative to GITHUB_WORKSPACE.
It would be great if we could have a strategy to support absolute paths, e.g. by:

• introducing a default-true "relative" property
• suggesting a way to change GITHUB_WORKSPACE to the empty string

I second this. At first I tried setting working-directory, which didn't work (Unexpected value 'working-directory'). Then I tried giving all paths as absolute paths, which failed on Linux/OSX with (Not Found) (yet reported success and created an empty zip!) and on Windows with ENOENT: no such file or directory (this time properly reporting the failure). Then finally stumbled on this issue, which gave me the solution.

I think supporting working-directory would be the way to go.

I also avoid working with relative paths as much as possible. Allowing the user to control the input/output paths explicitly with absolute paths not only affords the most flexibility but also the most clarity around what this action is doing.
