bug#50009: 28.0.50; add CRLF to outgoing ERC protocol logger lines

[dick]

Sigh, it pains me to have to add to the verbiage maelstrom that is debbugs
when the antiquity of GNU patch is self-evident.

A maintainer's sanity is inversely related to how much reading he has to do.
In a PR-based workflow, the changeset is unambiguous.  On a platform like
Github, the changeset is manifest (in pretty colors) from the "Files Changed"
tab in a PR submission.  Eleventh-hour revisions get incorporated without fuss
via the mild genius of git.

Here, OP has submitted several changesets, of which only the chronologically
latest he wishes the maintainer to consider.  To ascertain this fact, the
maintainer must read, and recall his happiness is inversely proportional to
how much reading he has to do.

In a cluster**** like bug#45474 where literally every one and their third
cousin is espousing a changeset, the maintainer not only has to read, he has
to decide, and that is a whole other circle of hell.  The programmer's
tendency to pontificate and obfuscate (of which the present missive is a fine
example) does not help matters.
