Revision 1.45, Tue Oct 17 09:52:11 2023 UTC (7 months ago) by nicm
Branch: MAIN
CVS Tags: OPENBSD_7_5_BASE, OPENBSD_7_5, HEAD
Changes since 1.44: +248 -611 lines
Update ncurses and associated libraries (form, panel, menu) to
6.4-20230826 (from 5.7-20081102).
Based on result from Thomas Dickey's ncu2openbsd script and then
modified. Switches to the upstream tput. Major bump for the ncurses
libraries and for libedit and libreadline.
Help from tb, millert.

/*
* Notes:
* The initial adaptation from 4.4BSD Lite sources in September 1995 used 686
* lines from that version, and made changes/additions for 150 lines. There
* was no reformatting, so with/without ignoring whitespace, the amount of
* change is the same.
*
* Comparing with current (2009) source, excluding this comment:
* a) 209 lines match identically to the 4.4BSD Lite sources, with 771 lines
* changed/added.
* a) Ignoring whitespace, the current version still uses 516 lines from the
* 4.4BSD Lite sources, with 402 lines changed/added.
