Fix determine whether a path is empty #57

Open Alex-duzhichao opened 2 years ago

If we call expand('%p') in a unnamed buffer, we will get an empty string "". shellescape("") returns an escaped string "''" which is not empty. So the determine whether a path is empty in current code takes no effect.

Determine the emptyness using result of expand('%p') fixes this bug.
