I normally use this hook:before-save-hook (delete-trailing-whitespace time-stamp copyright-update)
But this is not a good idea, if I use org-icalendar-export-to-ics, because the spaces at line ends are significant in an ics file. There is only a org-icalendar-after-save-hook (and not a org-icalendar-before-save-hook). Any elegant idea to retain the spaces (without customizing the before-save-hook for this)? Thanks for any help
