------------------------------------------------------------------------
Expected: When using the Customize interface to create/edit an Org
capture template, we expect to be able to specify a file to write the
captured item into using (according to the documentation) any one of:
* a literal filename
* a function
* a variable
* a form
But the Customize UI supports only the first of these. The attached
patch adds Customize support for the other three variants, in the proper
order (increasing generality/decreasing specificity).
Note that using Lisp to specify a capture template's target file using a
function, variable or sexp *does* work fine and as documented, except
that thereafter Customize fails to present the resulting variable
correctly; it reverts to showing the alist as one Lisp form. This patch
simply "catches up" the Customize UI with what Org can do and is
documented as doing.
As a workaround, I fell back on using the alternative 'function' target
specification method. That is, it's an alternative to 'file'; not to be
confused with the 'function' sub-method of 'file'. It took some rooting
around in source code for me to understand exactly what this function
has to do. It has to visit a file and optionally move point. Overkill
for my initial requirement, which was simply to produce a date-including
filename, but I made it work*, rather than lose the Customize UI. Anyway,
the documentation was too vague, and this patch also fixes that.
I have signed the FSF papers.
* pending your acceptance of this patch, at which point I can revert to
the simpler filename-producing function I wanted to use initially.
