wheels, always built locally, have different hashes than the files
downloaded from the index server and thus throw false hash mismatches.

``auto_confirm`` is True.
Refuses to delete or modify files outside of ``sys.prefix`` -
thus uninstallation within a virtual environment can only
modify that virtual environment, even if the virtualenv is

hashes to be known-good.
Hashes in URLs--ones embedded in the requirements file, not ones
downloaded from an index server--are almost peers with ones from
flags. They satisfy --require-hashes (whether it was implicitly or
explicitly activated) but do not activate it. md5 and sha224 are not
allowed in flags, which should nudge people toward good algos. We
always OR all hashes together, even ones from URLs.
