test-rename-merge2: make selected output less arbitrary
It's unclear why everything from the first 'updating:' line should be
ignored. The arbitrariness makes it confusing that changing the code
so e.g. the 'getting 8/f' line is printed later makes it disappear
completely from the ouput. The list of 'preserving x for resolve of y'
seems convered by the subsequent for loop in the test case. Perhaps
it's only copies that are of interests, so let's keep only that part.
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))
