[src/trunk]: src As described in tech-userlevel:
details: https://anonhg.NetBSD.org/src/rev/90abf77785ed
branches: trunk
changeset: 746300:90abf77785ed
user: christos <christos%NetBSD.org@localhost>
date: Fri Mar 27 15:11:57 2020 +0000
description:
As described in tech-userlevel:
- Modify the writing code to only write entries in the new
format for the terminal descriptions that require it.
- Store new format entries as <name>@v3
- Store old format entries with clamped values as <name> for
backwards compatibility
- Lookup first <name>@v3 and then <name> if that is not found.
- Don't create terminfo2 anymore; old programs keep working with
clamped entries, and new programs be able to use the wide
fields with using the original db file.
