add FIELD?=GLOB to git-annex view usage

And also to vadd usage.

Also added some other things to the usage that were omitted before to
save space.

Adding even FIELD?=GLOB made the git-annex --help list of commands grow
too wide for an 80 column display. So, removed the description of
parameters from that list of commands.
