Looks good! Does this fix #296, then? cc @iliekturtles

#296 resolved by this PR. I'll close. Thanks!

Oh wait, i just realized that it may not fix that issue, since this is meant to fix build logs, not source views. Still, i'll merge this; we can check out whether it fixes that issue once it's deployed.

Good point. I forgot to check the full context of the scss change and it only applies to the .recent-releases-container. The fix for #296 would need the change applied to pre elements in .package-page-container (~line 546). The change could be applied there, but a fuller review of all the pre styles is probably a better idea.
