Make pylint <dir> work like pylint <dir>/*.py

Most linters offer CLI syntax of linter

meaning lint all relevant files in a directory. Typically, users run linter ., to lint the current directory.

pylint rejects this for directories with no init.py, such as collections of standalone, one-off scripts. As a mitigation, we can use pylint *.py, but it would be nice to type pylint ., in keeping with conventional linter syntax.

Closing in favor of #352 (that is a newer issue, but with more discussion at hand)
