It should revert exactly the right code. If reversion didn't fix the problem, then surely the problem is not related to the reverted code, and the reversion should therefore be reverted. You reported that 7605060d51bbce88307c09bd2e9be60f2750ee3d worked and that its successor 2ff930d861b772466b9f6b95d1776696298f3e0b did not. Now that I look more carefully, though, I see that those two commits are not adjacent. (The commits are adjacent in the 'git log' output, but that output is a linearized version of a DAG. The parent of 2ff930d861b772466b9f6b95d1776696298f3e0b is actually 886ba068c82dcf5e0e2e1244bf99841d4ff5690c, its parent is 6593d73928da6c9fb1ccc57930566ddd2a37c737, its parent is be2ef629eea4bd4a7b16f6db91aab155db3489c7, and so forth. Please bisect based on this ancestor relationship, not based on 'git log'. In particular, if 886ba068c82dcf5e0e2e1244bf99841d4ff5690c fails to work then the reversion was surely unnecessary, and something else needs to be reverted. You said that Emacs worked for you on August 9. If 886ba068c82dcf5e0e2e1244bf99841d4ff5690c fails to work, I suggest bisecting based on master as of August 9 (commit b799cc271d69fc494da1fe04ca8ec6c529a19a19, say?), versus the failed commit 886ba068c82dcf5e0e2e1244bf99841d4ff5690c.
