My thinking is that "--oneline --show-signature" and "--oneline"
with log.showsignature set to true without "--no-show-signature" on
the command line should produce identical result.

The current definition of "--oneline" seems to me "the commit object
name and the log message is shown on a single line" (I consider that
the decoration given by "--decorate" is part of "commit object
name"), but there may be other things shown that may not fit on a
single line.

I do not terribly mind changing the definition of "--oneline" to
"what is output is ONLY the commit object name and the log message,
nothing else is shown", though.  After all, the output from "log" is
for human consumption, and it is a bug in the script if it is
depending on parsing the "log" output, so it is OK to change its
output to suit human needs, if necessary.
