Hi, I re-created the patch file by the instruction on "How to contribute to Org". Could someone please take a look and, if it is satisfactory, please help to apply it? I am used to Orgmode under Cygwin and sometimes uses ditaa for drawing diagrams. But without this patch, I have to switch to Windows native Emacs for calling ditaa. Many thanks Regards, Yujie 2013/7/12 Jambunathan K > > Sorry. >
