This method is only used once in this file and probably won't be needed anywhere
else...maybe I should just make it a lambda?

[Xiaocheng, 2017/04/07 23:42:24]

If it's used only once and internally, making it a lambda is better.

It's always good to keep header files small.

[rlanday, 2017/04/11 01:08:59]

I stand corrected, it's also used in
TextMatchMarkerList::SetTextMatchMarkersActive()

[Xiaocheng, 2017/04/11 01:26:01]

In this case, I don't have a strong preference.

I slightly prefer hiding it because of its long name.

This method isn't really an editing method...does this not belong here?

[Xiaocheng, 2017/04/07 23:42:24]

I think this method doesn't do much. We should make the callers call
Vector::appendVector directly.

It's better to use output to an empty DMV so that this function does not depend
on DML.

Btw, I think it's better to make it something like moveSorted/UnsortedMarkers.

It doesn't make too much sense to introduce a static private function.

Just hide it in an anonymous namespace in the .cpp file.

+      DocumentMarkerVector* markerList,
+      DocumentMarkerList::iterator beginIt,
+      DocumentMarkerList::iterator endIt,
+      unsigned startOffset,
