Dom Sekotill 31afbc760e Use path comparison not string comparison for paths
This will solve part of issue #4255 where WORKON_HOME is defined with a
trailing slash or not normalised in some way, as well as instances
where symlinks are used, and any other instances where constructed
paths don't exactly match even though they go to the same file.
