[PATCH] org-clock.el: clocktable ':formula %' now includes per-file time pct

[Alan D. Salewski]

* lisp/org-clock.el (org-clocktable-write-default): When ':formula %'
  is in-effect, show the per-file time percentage in the '%' column.

This change only has an effect when multiple files are contributing
to a given clocktable (such as when ':scope agenda' has been
specified).  The existing behavior is that such tables have an extra
'File' column, and each individual file that contributes has its own
summary line with the headline value '*File time*'.  Those summary
rows also produce a rollup time value for the file in the 'Time'
column.

Prior to this change, the built-in '%' formula does not produce a
calculation for those per-file times in the '%' column (the relevant
cells in the '%' column were blank).  With this change, the
percentage contribution of each individual file time to the total
time is shown.

The more agenda files you have, the more useful this behavior
becomes.
