Fix vertical split of screen command in Mac

Screen is a cool command to split the terminal. In Mac, however, only the horizontal split works. I searched the web for a long time and luckily find a way to fix this problem!

$ cvs -z3 -d:pserver:anonymous@cvs.savannah.gnu.org:/sources/screen co screen
$ curl http://old.evanmeagher.net/files/gnu-screen-vertsplit.patch > gnu-screen-vertsplit.patch
$ cd screen/src
$ patch < ../../gnu-screen-vertsplit.patch
$ ./configure --enable-locale --enable-telnet --enable-colors256 --enable-rxct_osc
$ make
$ sudo make install

Good luck to you all!
