[ostreambuf.iter.ops] not divided into subsections as [istreambuf.iter.ops]

[lynnboy]

there are several [istreambuf.iterator::op...] sections under [istreambuf.iterator],
but there is only a combined [ostreambuf.iter.ops] section under [ostreambuf.iterator].
This is inconsistent.

Consider split it into subsections.

Also: consider change :: into . and * into star in section labels

I don't think we are going to change stable names.

[lynnboy]

But we've already made :: -> . for [string.xxx].

[tkoeppe]

@lynnboy: Wasn't that for new content post-C++14? Things that were added in this revision can still be changed, indeed.

[cpplearner]

The change from [string::xxx] to [string.xxx] is made in 0b5bcd5.

[tkoeppe]

I see. I guess we do change stable names then...

[jensmaurer]

The stable names are really bad, and those single-paragraph descriptions should never have gotten separate sections to start with.

[Eelis]

[reverse.iter.ops] also has many single-paragraph subsections for individual operators. So possibly that one could be cleaned up as well.

[jensmaurer]

This seems to be a pervasive issue in that area; see [front.insert.iter.ops] and [back.insert.iter.ops]. The [reverse.iter.ops] that you mentioned are more than half a page, though, so some kind of subdivision (e.g. "comparison operators", "arithmetic") might be worthwhile.

In short, all of [predef.iterators] is affected, and we should come up with a common approach for that subsection instead of fixing individual issues.

@zygoloid, what do you think?

[jensmaurer]

Editorial committee consensus: Fold mini-sections for operators and rename "::" in stable names.
