* 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.
