Hi,

After recently updating my OS and checking out the latest Emacs/gnus
from bzr the text in my summary buffer which indents articles to
indicate threads is now underlined.  For example when I do

  (buffer-substring (point) (+ 4 (point)))

with the point in a bit of thread indentation (specifically a group of
`gnus-sum-thread-tree-indent' characters), I get the following

  #("    " 0 4 (gnus-face t face italic gnus-number 18))

However none of those indicate to me that the characters should be
underlined, and I am unable to dig further as gnus-face seems to be
undefined.

Any help on how to remove this underlining would be greatly appreciated.

Thanks -- Eric
