Inconsistency in command behaviour

[shubhamshuklaer]

ghi open sample_title -m "sample_description" will open an issue with title as "sample_title" and description as "sample_description". However ghi milestone sample_title -m "sample_description" creates a milestone with title "sample_description" and empty description.

Though default behavior of ghi open is opening issue, but default behavior of ghi milestone is list milestones, but still consistency is good.

Same case with edit sub-command too.
