[PATCH 01/27] detect command: Drop -e option

[Sascha Hauer]

The -e option is not that useful. Normally, when a device cannot
be detected, then there should be no reason to not try to detect
other devices. When a user is interested in a particular detect
result, detect can still be called with that (and only that)
device.
We could also argue that the user should not care about the result
of the detect call, but instead check if the desired device is
present afterwards.
Drop handling of the -e option, but still ignore it for compatibility
reasons.
