[bug#72867] [PATCH] gexp: Make 'local-file' follow symlinks.

Hello Florian,

suggestions I would hardly have made this patch.
Thank you for all this.

I was thinking about making a test to 'local-file'. It is natural
taking into account the problem this patch solves sits in
'local-file' bad behavior. But 'current-source-directory'
is fine already.
