optimize `hold` #531

Closed ekipan closed 1 year ago

ekipan commented 1 year ago

Instead of moving characters forward, store them going backward.

Though I guess the failure mode is quite different. 35th hold used to just trash <#, now it bops holdp's MSB I think? So subsequent holds are probably a bit more destructive.

You could make it less unpredictable by moving holdp after the buffer, if you care enough.

It does not matter so much to me, if it fails one way or another :-) I think it is fine the way it is. Thank you for the contribution!
