xerrors: gobble colon and newline in edge cases

We gobble newlines at the start of a detailed
section, at end before a new message, but not
at the end of a message. This CL add that.

Also, we should not print the colon after the last
non-detailed message if the detailed message
consists solely of newlines that are gobbled.
