Assorted bug target manipulations and queries.
If no target is specified, the bug's current target is printed. If
TARGET is specified, it will be assigned to the bug, creating a new
target bug if necessary.
Targets are free-form; any text may be specified. They will generally
be milestone names or release numbers. The value "none" can be used
to unset the target.
In the alternative `be target --resolve TARGET` form, print the UUID
of the target-bug with summary TARGET. If target is not given, return
use the bugdir's current target (see `be set`).
If you want to list all bugs blocking the current target, try
$ be depend --status -closed,fixed,wontfix --severity -target \
$(be target --resolve)
If you want to set the current bugdir target by summary (rather than
by UUID), try
$ be set target $(be target --resolve SUMMARY)
