[bug-recutils] Work needed in the user manuals

[Jose E. Marchesi]

Hi John.

The GNU Recutils user manual lives in the file doc/recutils.texi.  The
problems we currently have with this manual are mainly two:

- The manual is incomplete and does not currently cover some of the new
  facilities that will go in 1.6.  The list of not covered functionality
  is:

  + Grouping (option -G|--group-by to recsel).  There is a section
  called "recsel Grouping" which I started, but it is not finished.

  + The aggregated functions.  This would ideally go in a dedicated
  section after the section on grouping.

  + Joins.  We would need a section "recsel Joins" or something.

- Some people complained about the manual not being tutorial-like
  enough, meaning that it is difficult to get started in using the
  tools.  It would be probably good to re-structure it.

Additionally, the Emacs mode rec-mode.el is now getting stable and
better.  I started a skeleton of a manual for the mode at
doc/rec-mode.texi, but we need to write it down.
