/*
* cut --
* Put a range of lines/columns into a TEXT buffer.
*
* There are two buffer areas, both found in the global structure. The first
* is the linked list of all the buffers the user has named, the second is the
* unnamed buffer storage. There is a pointer, too, which is the current
* default buffer, i.e. it may point to the unnamed buffer or a named buffer
* depending on into what buffer the last text was cut. Logically, in both
* delete and yank operations, if the user names a buffer, the text is cut
* into it. If it's a delete of information on more than a single line, the
* contents of the numbered buffers are rotated up one, the contents of the
* buffer named '9' are discarded, and the text is cut into the buffer named
* '1'. The text is always cut into the unnamed buffer.
*
* In all cases, upper-case buffer names are the same as lower-case names,
* with the exception that they cause the buffer to be appended to instead
* of replaced. Note, however, that if text is appended to a buffer, the
* default buffer only contains the appended text, not the entire contents
* of the buffer.
*
* !!!
* The contents of the default buffer would disappear after most operations
* in historic vi. It's unclear that this is useful, so we don't bother.
*
* When users explicitly cut text into the numeric buffers, historic vi became
* genuinely strange. I've never been able to figure out what was supposed to
* happen. It behaved differently if you deleted text than if you yanked text,
* and, in the latter case, the text was appended to the buffer instead of
* replacing the contents. Hopefully it's not worth getting right, and here
* we just treat the numeric buffers like any other named buffer.
*

* like appends to buffers that are used multiple times.)
*
* Otherwise, if it's supposed to be put in a numeric buffer (usually
* a delete) put it there. The rules for putting things in numeric
* buffers were historically a little strange. There were three cases.
*
* 1: Some motions are always line mode motions, which means
* that the cut always goes into the numeric buffers.
* 2: Some motions aren't line mode motions, e.g. d10w, but
* can cross line boundaries. For these commands, if the
* cut crosses a line boundary, it goes into the numeric
* buffers. This includes most of the commands.
* 3: Some motions aren't line mode motions, e.g. d`<char>,
* but always go into the numeric buffers, regardless. This
* was the commands: % ` / ? ( ) N n { } -- and nvi adds ^A.
*
* Otherwise, put it in the unnamed buffer.
