less 381
Over three years ago the less maintainer said he'll add these fixes.
Nothing happened, so we do it ourselves.
Thanks for the report and the patch!
revision 1.7
date: 2004/04/08 15:18:28; author: millert; state: Exp; lines: +5 -7
When reallocating the line buffer, double the existing buffer
size instead of just incrementing it by LINEBUF_SIZE and use realloc()
+ memset() instead of calloc() + memcpy(). Prevents excessive resource
usage when displaying very long lines. OK deraadt@, krw@ and otto@
