about mutt-patch sidebar indent level

[Chen Wei <weichen302@aol.com>]

Dear list:
In mutt-patch's sidebar(debian squeeze), some folders are
indented, they look like:

  comp.lang.python
Debian-User
Inbox
Spam

those folders are at same level, there are no sub folders, I notice
all indented folder have "." in their name, if I add "." to those
un-indented folder, they will be indented as well. For every "."
in folder name, the folder is indented one character to the right.

how to make those folder indent to same level?
