Argh. I forgot to mention that in the cover letter. Yes, I added
the whitespace intentionally for exactly that reason.

That, of course, is correct. My intention was to make the code simpler
but I can see that people would be confused about the whitespace.

How about this?

			fprintf(stderr,
				_("hint: Waiting for your editor to close the file..."));
			if (is_terminal_dumb())
				/*
				 * A dumb terminal cannot erase the line later on. Add a
				 * newline to separate the hint from subsequent output.
				 */
				fprintf(stderr, "\n")
			else
				fprintf(stderr, " ")

Can you squash that if you like it?

Thanks,
