[PATCH 0 of 4] patchbomb: reduce cc prompts; documentation and help tweaks

[Christian Ebert]

Hi,

Here are 4 patches concerning patchbomb:

1. removes a description specific to patchbomb behaviour from
   hgrc.5.

2. documents the use of [patchbomb] as configuration section.

3. changes patchbomb behaviour wrt to the Cc prompt:
   prompts are reduced to those cases when Cc is
   a) not configured AND b) --to option is not given.

4. is a cosmetic change and can of course be left out.


After discussing 3. on irc and lengthy testing this behaviour
change makes the most sense to me:

a) it does not introduce any magic evaluation of hgrc like my
   previous patch does ("cc =" suppresses prompt), even though
   it made some sense from the user's pov: "I want to _configure_
   whether or not I'm prompted for Cc. The clean way would then
   be to have a (additional) boolean like `askcc'.

b) the behaviour change is minimal: only 2 cases.

For reference I include the table from the 3rd patch's
description again here (* marks behaviour change):
