Re: [Erc-discuss] [PATCH] Many fixes to erc-track.el

[Jeremy Maitin-Shepard]

My previous description of the patch was incomplete; I forgot to mention
one additional feature it adds.

- Adding a supported value for `erc-track-position-in-mode-line' that
  specifies that the tracking information should not be added to the
  mode line at all.  The value of nil is used to indicate that the
  information should not be added at all to the mode line.  The one
  issue is that the existing behavior was for all values (including nil)
  of `erc-track-position-in-mode-line' other than `before-modes' or
  `after-modes' to indicate that the information should be added "After
  all other information"; this behavior is now selected only by the
  value `t'.  Furthermore, the customize specifications used `nil' as
  the value for the "After all other information" option.  Thus, this
  patch results in a change of behavior for users that selected the
  "After all other information" using customize, or manually set the
  variable to nil.  In theory, though, since the documentation for the
  variable states that any value other than `after-modes' or
  `before-modes' specifies the "After all other information" option, any
  additional option added for this variable would be potentially
  backwards incompatible, and using t for "After all other information"
  and nil for "Don't add to mode line at all" makes a lot more sense
  that the reverse association.  It doesn't really matter to me what is
  chosen in the end, though.
