[O] How can I stop org-agenda-write from overwriting existing files.

[Rainer Stengele]

Hi all,

constructing an agenda with clocktable for 1 month takes some time here..
Writing the agenda to "/patch/agenda-201302.html" works fine.
Then creating the agenda for the previous month I also want to write it
to a html file. I would like to use "/patch/agenda-201301.html" for it.
providing "/path/ag" and pressing TAB expands the existing path and -
overwrites the uniquely found file!

How can I stop org-agenda-write from overwriting existing files?
Should we consider to introduce an option instead of advising the function?


Thanks,
Rainer
