Revert "force grid size. Closes T662"

This reverts commit 98fd3b0a118a3035e119f91091c562f2671bc3a1.

this causes terminology to no longer handle resizes at all! :( pretty
bad!
improved manpage in formatting and a small bugfix

 - The example code for the escape terminology command was rendered
   incorrectly in the manpage, this is now fixed
 - the formating was wrong rendered viewing with man, having too much
   newlines that broke the structure, this is better aligned now
skip buffer when dcs parsing overflows. Closes T932
