description:
>From Ingo Schwarze, based on changes from Kaspars Bankovskis:
 * Document error handling of el_init(), el_set(), el_source(),
   and history_init().
 * Fix a typo an improve punctuation below H_SETUNIQUE.
 * The ellipsis already implies "optional", no need for [].
 * Sort options in editrc(5).
 * Prevent e.g. rom being misconstrued as the end of a sentence.
 * Drop a useless duplicate .Ar macro.
 * Put telltc in its proper place in the alphabetical order.
 * A few typos in vi editor command names.
 * Some missing vi editor command names.
 * Some missing author macros.
