In the RMAIL-summary columns for author in EMACS how do you expand,
lengthen, adjust the RMAIL-summary columns for authors?... to include
more of the characters of the author.

Example

Message  Date    Author            Number  Subject
number                             of
                                   lines

You don't, not without hacking the sources, anyway.  See the function
rmail-make-basic-summary-line (in rmailsum.el) where all these column
widths are hard-coded.  Also note that various other parts of
rmailsum.el, such as rmail-summary-font-lock-keywords, know about the
precise formatting and will probably break if you modify the format
without adjusting those other features as well.

Sorry.
