histedit: remove history_source

History source is polluting the commit messages. This is
visible when converting the repository to git but the fact that
it stays in the history is bad enough by itself. This patch
removes the needless logging. I do not know why you would need
this but it possibly could be non-default, activated by an
argument to the histedit command.

     This function ensure we apply the same treatment to all changesets.
 
-    - Add a 'histedit_source' entry in extra.

     Note that fold have its own separated logic because its handling is a bit
     different and not easily factored out of the fold method.
