transaction: really fix _addbackupentry  key usage (issue4684)

The fix in fd905b2bea59 is actually wrong. We now use the filename to match what
'_addentry'. This whole untested code is quite suspicious. This seems to point
that no one is ever running 'tr.find' for a backup file.

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 in globalvars
        except Exception, inst:
            print repr(inst)
