Document mixed tab/space indentation may be used for multiline wrapping in C++ usage guidelines

• See Add disk size display to texture preview metadata godot#117071 (comment).

One example of this can be found here: https://github.com/godotengine/godot/blob/a1eaac8171a53e5a74cd511bc144bd28afc4c7ff/editor/export/editor_export_platform_apple_embedded.cpp#L2195-L2201

The example you linked isn't an example where arguments are space-aligned. It's a single argument string, where the string parts are split over several different lines. The string itself is space-aligned.
I'm not sure we have space aligning of arguments in the codebase, or at least I've never seen it.

I've found other examples that aren't concatenated strings:

Your linked examples all appear to use tabs to indent instead of spaces.

There are spaces in the continuation indent, as seen here:

How debatably nasty actually. Albeit unlikely done by ourselves, changing the indentation size ruins the alignment, unless the number of spaces and tabs were the same. I would not encourage this.
