; Address some ambiguities in ERC's documentation

* doc/misc/erc.texi: Change name of example function from
`erc-my-enable-read-indicator-on-join' to
`erc-my-enable-keep-place-indicator-on-join'.  Fix example functions
`erc-cmd-TRACK' and `erc-cmd-UNTRACK' to work with server buffers as
well as target buffers.
* etc/ERC-NEWS: Revise `keep-place' entry and make headlines less
redundant.
* lisp/erc/erc.el (erc-accidental-paste-threshold-seconds): Fix
portion of existing wording that was more likely interpreted as a
single multiline submission, whereas the intended meaning is three
separate submissions.
