I'm wondering how I search history for any changeset that contains a change (diff) between the file and it's previous version with the word "foobar" in it.
In other words, and more specifically, I want to find the changeset that removed a subscription to an event. Clearly the change won't be in the class raising the event, and because the event subscription is now gone, I don't know where it used to be.
I can probably narrow this down to a few hundred files, but viewing their individual history and then performing a difference on each seems excessive. The TF history command, even in detailed view, only shows me file names.
tf history /format:detailed *.* /noprompt /stopafter:1
Is there an undocumented uber-detailed output that shows a diff of each file with it's previous version?
