* Historical whackadoo. The dot command `puts' the numbered buffer
* after the last one put. For example, `"4p.' would put buffer #4
* and buffer #5. If the user continued to enter '.', the #9 buffer
* would be repeatedly output. This was not documented, and is a bit
* tricky to reconstruct. Historical versions of vi also dropped the
* contents of the default buffer after each put, so after `"4p' the
* default buffer would be empty. This makes no sense to me, so we
* don't bother. Don't assume sequential order of numeric characters.
*
* And, if that weren't exciting enough, failed commands don't normally
* set the dot command. Well, boys and girls, an exception is that
* the buffer increment gets done regardless of the success of the put.
