scmutil: extend termwidth() to return terminal height, renamed to termsize()
It appears crecord.py has its own termsize() function. I want to get rid of it.
The fallback height is chosen from the default of cmd.exe on Windows, and
VT100 on Unix.
from __future__ import absolute_import, print_function
import sys
globalvars = {}
lines = sys.stdin.readlines()
while lines:
l = lines.pop(0)
if l.startswith('SALT'):
print(l[:-1])
elif l.startswith('>>> '):
snippet = l[4:]
while lines and lines[0].startswith('... '):
l = lines.pop(0)
snippet += l[4:]
c = compile(snippet, '<heredoc>', 'single')
try:
exec(c, globalvars)
except Exception as inst:
print(repr(inst))
