Try to predict command

[orsinium]

1. If one word passed as a command, but there is no command with this name, it is possible that missed the first word. For example, if called command shell it means venv shell.
2. If command not found, possibly it's a misspelling. For exapmle, venv shll means venv shell. There is the simplest way to do it:

from collections import Counter

def similar(command1: str, command2: str) -> bool:
  c1 = Counter(command1)
  c2 = Counter(command2)
  c = (c1 - c2) + (c2 - c1)
  diff = sum(c.values())
  return diff < 2

See #119 for context.
