Bug#376293: debbugs: Add chaining options to "block" command (when A is closed, it closed B ...)

[Jari Aalto <jari.aalto@cante.net>]

Package: debbugs
Severity: wishlist

An example:

    - Bug 123456 has been filed to package A
    - In order the A to behave correct, B (say; library) needs to be updated
      to latest upstream version.

So, until new B is packaged, it blocks marking bug in A (123456)
done. 

SUGGESTION

Add chainign possibility to the BTS system, where the "block" command
will chain the bug to close when the one pointed by "by" is marked
done.

Current syntax:

  block A by B

New syntax:

  block A by B [do <action>]

Where <action> would be any valid BTS command. An example:

  block A by B do close A

Or:

  block A by B do tags A + pending
