buck test -e no longer means exclude

[spearce]

In c14981b Simon changed -e to mean --emulator instead of --exclude. This was a surprising behavior change. :-(

Sorry about that. We decided to go with the naming convention of adb for identifying which device to target when running tests since we had a clash with "-e" between the (un)install commands and the running test one. If you can think of a better short-name to use for "exclude", I'd be happy to add something back.

If not, is there anything to be done for this issue? I'm not sure if you're requesting us to change it back or just informing us that we should be better at announcing changes (or both)

It would be nice if options don't change behavior, and if they do if its better communicated. But I understand you don't want to change it back so we are stuck with --exclude.

It's a good point about the communication of changes, particularly of our UI. Thanks for bringing it up. @bolinfest, perhaps we should start keeping some sort of changelog?
