edit: don't change terminal mode if sedit would fail to read file

Failing to read the file, e.g. because the file is actually a directory
will normally result in an appropriate error message.

When using vi or sedit however, we change cursor position beforehand
and then directly exit, which messes up the terminal output and
can even make the shell unusable (as on my Laptop's UEFI).
Move the check earlier to avoid this.
