Passing -e and . as separate arguments also works:

$ pip install -e .

tox3 works around that by turning '-e .' into '-e.'

This is the downside of rewrites. This bug have already been fixed once. Now we have to fix it again.

Lines 177 to 187 in 32e74a8

	# we need to process options, in case they contain a space,
	# as the subprocess call to pip install will otherwise fail.
	# in case of a short option, we remove the space
	for option in tox.PIP.INSTALL_SHORT_OPTIONS_ARGUMENT:
	if name.startswith(option):
	name = "{}{}".format(option, name[len(option) :].strip())

It's a trade-off, on one end some old bugs might creep in, but on the upside, the codebase will be in a better place after it. No need to lament over this. For example, here I think tox 3 solution is incorrect, we should turn this into Passing -e and . as separate arguments.

This has been fixed by #1991 - thanks a lot, @gaborbernat!
