[New-bugs-announce] [issue38294] re.escape seems to miss some importante regex characters

[Ricardo Bánffy]

New submission from Ricardo Bánffy <rbanffy at gmail.com>:

Under Python 3.6, re.escape escapes "/"

In [1]: import re

In [2]: re.escape('http://workday.com')
Out[2]: 'http\\:\\/\\/workday\\.com'

Under 3.7 and 3.8, "/" is not escaped.

In [1]: import re

In [2]: re.escape('http://workday.com')
Out[2]: 'http://workday\\.com'

Is this change deliberate? For a minor release (3.6 to 3.7) this broke some code that generated `sed` commands to run on a remote server.
