Allows better formatted and commented log_handler items in
configuration files: configparser allows multiline values and
interspersed comments (stripping out comment lines), but while it
removes indent it leaves the linebreaks, so e.g.
foo =
bar,
# qux
quux
when parsed and split on "," results in `['\nbar', '\nquux']` which is
obviously an issue for logging (as it assumes the leading `\n` is part
of the logger name proper).
Since log_handler items can be fairly long and are not necessarily
self-descriptive as to *why* they were selected for re-configuration,
allowing one per line & comments is helpful.
