Lynx and Slang 1.3.8


For about two years I've been compiling lynx with s-lang on Solaris2 and
FreeBSD (presently Solaris2.5 and FreeBSD 2.2.7). I've never had a problem
and I've always had better results with s-lang than with Solaris' curses or
ncurses. With s-lang 1.3.8 I got a problem for the first time. The same
version of lynx compiled with s-lang 1.3.7 and 1.3.8 give different results.
The one compiled with 1.3.8 gives me some garbage on the screen on the
FreeBSD system. It seems that the problem is related to how the screen is
cleared. I've always used the "ut" capability (screen erased with background
color) in my termcap on the FreeBSD system ("bce" in Solaris' terminfo). When
I remove "ut" from my termcap the problem with s-lang 1.3.8 disappears and I
get no garbage on the screen. On the Solaris 2.5 system I have no problems.

I did some tests by running, on the FreeBSD system, the same version of lynx
compiled with s-lang 1.3.7 and 1.3.8, with and without "ut" in my termcap. I
used "script" to log the codes sent to the screen. To make it easier to
compare the files I replaced the ESC code with the "ESC" word, and the
trailing spaces with the "%" character. Here are the results:
