GNU Screen v.4.8.0

Hello everyone,
I'm announcing availability of GNU Screen v.4.8.0

Screen is a full-screen window manager that multiplexes a physical
terminal between several processes, typically interactive shells. 

This release
  * Improves startup time by only polling for already open files to
  * Fixes:
       - Fix for segfault if termcap doesn't have Km entry
       - Make screen exit code be 0 when checking --version
       - Fix potential memory corruption when using OSC 49

As last fix, fixes potential memory overwrite of quite big size (~768
bytes), and even though I'm not sure about potential exploitability of
that issue, I highly recommend everyone to upgrade as soon as possible.
This issue is present at least since v.4.2.0 (haven't checked earlier).
Thanks to pippin who brought this to my attention.
