hey. i found these two patch's useful. i'd like to offer them back if you find them useful. the alias of UnpatchedGem#gem as UnpatchedGem#rubygem is because under certain circumstances it seemed to resolve to Kernel#gem from rubygems. the second patch supports an IO representation of Gemfile.lock,so @root is considered nil and the contents are read via #read before being passed into the lockfile parser. the old behavior is the same if the argument isn't IO-like. thanks!

btw i plan to release the tool i made these changes for as open source too, but it's not finished yet.

I'm doing some issue gardening 🌱🌿 🌷 and came upon this issue. Since it's quite old I just wanted to ask if this is still relevant? If it isn't, maybe we can close this issue?

By closing some old issues we reduce the list of open issues to a more manageable set.
