Subject: [Patch] Add another bullet type (→)
Date: Fri, 13 Mar 2009 23:58:03 +0100	[thread overview]

Hi All,

I tend to use a right arrow (→, U2192) from time to time in plain
lists to separate normal item from conclusions / next actions etc.:

  - Topic
    - Fact 1
    - Fact 2
    → Conclusion

I would appreciate it if org-mode could support this type of bullet
point.  The attached patch implements what I had in mind.

I'm not sure if the adaptation in /org-cycle-list-bullet/ is useful
for others --- I don't use the arrow for many items in a list, but
only single ones --- But I included it in the patch for completeness.

(Also, there may be better ways to encode unicode chars in regexp than
using the utf-8 encoding, that the patch uses.)

Cheers,
Martin
