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