When advice.waitingForEditor configuration is not set to false, we show
a hint telling that we are waiting for user's editor to close the file
when we launch an editor and wait for it to return control back to us.
We give the message on an incomplete line, expecting that we can go back
to the line and clear the message when the editor returns successfully.
However, it is possible that the editor exits with an error status, in
which case we show an error message and then return to our caller. In
such a case, the error message is given where the terminal cursor
happens to be, which is most likely after the "we are waiting for your
editor" message on the same line.
Only clear the line when the editor returned cleanly, and otherwise,
complete the message on the incomplete line with a newline before giving
the error message.
While we're here, make the error message follow our CodingGuideLines.
