New submission from Serhiy Storchaka:
$ PATH= /usr/bin/which python
$ PATH=: /usr/bin/which python
./python
$ PATH=/usr: /usr/bin/which python
./python
>>> shutil.which('python', path='')
'/usr/bin/python'
>>> shutil.which('python', path=':')
'python'
>>> shutil.which('python', path='/usr:')
'python'
First, I propose interpret path='' as an empty path, not as a default path (we
have None for this). However the interpreting of an empty directory in
non-empty PATH can be platform-depending.
