windows: removed duplicate termwidth definition Changeset dbf91976f900 caused this when the "from win32 import *" line was replaced with explicit import statements: the wildcard import was at the bottom of the file and so windows.termwidth was overwritten by win32.termwidth as indented, but the new explicit import statements were at the top and so win32.termwidth got lost. With the switch to ctypes, win32 can always be imported and so the fallback termwidth in windows is no longer needed.

obsolete: obsstore.add now takes a list of markers. This allow efficient IO and it greatly simplify the merging of markers.
