   The "a .. "z and "1 .. "9 buffers are part of historical `ex` and `vi`, see SUS   
   https://pubs.opengroup.org/onlinepubs/9799919799/ buffer definition.   
      
   I used to work on Mortice Kern Systems maintaining their DOS `vi` while we were   
   balloting POSIX.2. The named buffers were part of the historical `vi` and the   
   MKS independent clone.   
      
   As for the OP, deleting / changing always included a yank into the numeric   
   buffers.  That is historical behaviour and documented in SUS.
