[emacs-wiki-discuss] emacs-wiki: backlink naming fix and parental exclusion code

[Jim Ottaway]

I found a problem with the backlink creation: the code used the
function buffer-name for the name of the parent; but this might not
return the actual emacs-wiki page name: it may have been renamed
uniquely [i.e. it could be FooBar<1> or FooBar<wiki>, etc., if another
buffer is already called FooBar].  This patch modifies the code to use
emacs-wiki-page-name to get the link name of the parent.

I have another patch that modifies the behaviour of backlink creation
so that one can exclude backlinks on the basis of the parent name as
well as the child name.  I find this useful for planner day pages,
since one may not want to have a backlink to these, while one does
want backlinks to plan pages.

By default the regular expression used,
emacs-wiki-exclude-backlink-parent-regexp, matches no name.  I have it
set to planner-date-regexp as part of my planner configuration:

;; modify backlink option for planner pages [stops backlinking from
;; day pages]
(add-to-list 
 'planner-custom-variables
 (cons 'emacs-wiki-exclude-backlink-parent-regexp planner-date-regexp))

(planner-option-customized 'planner-custom-variables
                           planner-custom-variables)


I also tidied up the function a bit, and moved backlink searching
and creating to separate functions so that they may be used elsewhere
[in, for example, a reparenting function that I started writing
earlier today].
