Currently, the `edit` command does not allow the following:

• Opening an empty "command" (i.e., just typing `edit`)
• Opening strings that may look like a JavaScript variable, but are not.
• Strings that do not contain spaces or are not quoted.
  Works: edit "asd"
  Works: edit asd asd
  Does not work: edit asd
  Does not work: edit asd_asd

Since edit is being used as a connection from Mongo to $EDITOR, this functionality should be enabled.
