help: add a mechanism to change flags' help depending on config

It seems reasonable to have a similar mechanism for the rest of the
help, but no such thing is implemented.

The goal is to make the help of commands clearer in the presence of
significant default changes, like tweakdefaults or with company-wide
hgrcs. In these cases, a user looking at the help of a command doesn't
exactly know what his hgrc is doing.

Apply to this to the --git option of commands that display diffs, as
this option in particular causes confusion for some reason.

      rebase        command to move sets of revisions to a different ancestor
  
  (use 'hg help extensions' for information on enabling extensions)

Make sure that we don't run afoul of the help system thinking that
this is a section and erroring out weirdly.

  $ hg .log

Checking that help adapts based on the config:

  $ hg help diff --config ui.tweakdefaults=true | egrep -e '^ *(-g|config)'
   -g --[no-]git            use git extended diff format (default: on from
                            config)

this is a section and erroring out weirdly.
