nnimap subfolder problem

[Nicolas KOWALSKI <Nicolas.Kowalski@imag.fr>]

Hello.

At work, I use the nnimap backend, which "talks" to an UW-imapd
server. My folders are stored using subfolders, like the following:

  [ Misc -- 0 ]
        0: INBOX
        0: mail/drafts
        0: mail/sent
        0: mail/templates
  [ Personal -- 0 ]
        0: perso/famille
        0: perso/misc
  [ VERIMAG -- 0 ]
        0: verimag/hardware


My problem is : when I try to rename (G r) the group "perso/famille"
to something like "perso/famille/misc", Gnus tells me the group has an
invalid name...I suspect Gnus to not tolerate '/' characters in group
names, but that is what I need in my case.

Any idea(s) ?

Thanks in advance,
Nicolas.

PS : I tried to rename "perso/famille" to "perso.famille", this works;
     but then I can not rename it to use subfolders 
     ("perso/famille/misc").

PS 2: when I use nnml or nnfolder backends, Gnus stores groups using
subdirectories for group names like "foo.bar.geez" (gives
foo/bar/geez). Is it possible to use the same functionnality for
nnimap backend ?
