There's a catch to doing this. I've meant to (and put off for) quite a
bit to build a command that lets you easily see in which revisions a
"file" was changed.

Aye. I think this would be "good enough" for replay --skip-present.

Though I'm in favor of this, actually it can get to be quite a bit more
expensive than this. Though it wouldn't be this bad for small/medium
sized projects, larger heavily developed projects will see a
concatenated patch-log on the order of 5-6 megabytes per working
copy/revision in the library.
