* Stop trimming preceding and suffixing spaces from editor filenames
In #5702 it was decided to trim preceding and suffixed spaces aswell as / from
editing file filenames. This was because at this point in time the url-safety of
Gitea was much poorer.
We can now drop this requirement and file editing should work correctly.
