The current header formatting is a giant format string that changes
global state during the format process.
Make the following changes:
- use sbuf to build up the header rather than use the above
pseudo-dynamic one
- Change name length to 10
- Reduce size of RES and SIZE by making humanize more aggressive
- Restore a version number line to the copyright. This may be required
by the copyright (and may not be; its unclear)
This is also a pre-req to implementing TOPCOLOR from newer versions of
top(1)
