Describe the feature or problem you’d like to solve

assuming cli is the root of the local repo
current functionality:

C:\Users\User\Desktop\cli\pkg\cmd\browse> gh browse pkg\cmd\browse\browse.go

This seemed like a lot of typing for a directory I am already in

Proposed solution

relative path starts with "\"

C:\Users\User\Desktop\cli\pkg\cmd\browse> gh browse \browse.go

absolute starts with folder or file name

C:\Users\User\Desktop\cli\pkg\cmd\browse> gh browse api\cache.go

Additional context

Not sure if this is possible given the current code, but I found this which may help

C:\Users\User\Desktop\cli\pkg\cmd\browse> git rev-parse --show-prefix
pkg/cmd/browse/
