Sigh. ;)
At this point in my Python programming I intuitively understand what splitlines
does, but every time we try to explain it in detail it gets messier and
messier. I wasn't really happy with the addition of that sentence about split
in the first place.
I don't understand what your splitlines examples are trying to say, they all
look clear to me based on the fact that we are splitting *lines*.
I don't find your proposed language in the patch to be clearer. The existing
sentence describes the concrete behavior, while your version is sort-of
describing (ascribing?) some syntax to the line separators ("does not
delimit"). The problem is that there *is* a syntax here, that of
universal-newline-delimited-text, but that is too big a topic to explain in the
splitlines doc. There's another issue for creating a central description of
universal-newline parsing, perhaps this entry could link to that discussion
(and that discussion could perhaps mention splitlines).
The split behavior without a specified separator might actually be a bug (if
so, it is not a fixable one), but in any case you are right that that
clarification should be added if the existing sentence is kept.
