[Orgmode] Problem with hyperlinks containing brackets

[Paul R]

Hello,

I was playing with org hyperlinks facility, which is obviously amazing
just like org-mode itself, and I faced a problem. I own a fairly
standard Gmail account, and read it though IMAP in gnus. The resulting
group name is for example "gnus:nnimap+gmailPerso:[Gmail]/Sent Mail".

Whenever I want to make a link to it, the link content would be, for
exemple :

    "gnus:nnimap%2BgmailPerso:%5BGmail%5D/Sent%20Mail#1414"

which is the same with the brackets encoded and a message id.

Unfortunatly, this link would not open in gnus. It will apparently try
to find a group called "gnus:nnimap+gmailPerso:[Gmail" (this is, stop at
closing bracket) and will fail. Any idea on how to solve that please ?
As a workaround, I'd be happy to be able to rename groups to something
shorter, but I can't figure how (this is an OT gnus question).

I'm using GNU/Emacs 23 cvs of today, with bundled Gnus 5.13 and latest
org-mode.
