Hello all,

I quess the theme in this pull request is performance. More than half of
the patches will make commands to do stuff quicker, either by printing
with better functions or stopping to do things that are unnecessary. If
I did not misread my rather unscientific speed up measurements impact to
hexdump(1) and more(1) was greatest.

The following changes since commit 81499ab24e15532a8252c1e527d3301d9309c31e:
