[slang-users] Screen wider than 256 chars

[Thomas Glanzmann <sithglan@xxxxxxxxxxxxxxxxxxxx>]

Hello,
I have resolution of 265x91 (chars) in my xterm. slrn/Slang SEGFAULTS
because some has defined in /usr/include/slang.h:

	/* Maximum size of display */
	#define SLRL_DISPLAY_BUFFER_SIZE 256

which isn't exactly true. :-)

some information of my valgrind run:

/home/cip/adm/sithglan/work/valgrind-2.1.2/bin/valgrind --tool=memcheck \
	--run-libc-freeres=no --num-callers=10 --show-reachable=yes \
	--leak-check=yes --error-limit=no --log-file=/tmp/valgrind src/slrn

just use a big screen and open a group with several thousand messages and you
get an instead segfault.
