Linking to current directory: ./ vs nothing

When linking within the same directory, is there any reason to use

See [foo](./foo.md)

vs

See [foo](foo.md)

Hello @tomcam,

To my knowledge they’re both identical in functionality. The only time I can think of where ./ really comes in handy is if you’re creating a link for the current page as it eliminates the need to write index.html and such to refer to the current directory.
