[sylpheed:32351] subjects of too deep threads are not visible

[Evgeni Golov]

Hi,

my laptop has a resolution of 1024x768, which makes it hard to follow
threads (mostly patch series on mailing-lists), as the subject isn't
displayed properly after a certain depth.
You can see the result here:

Would it be possible to display the subject of such messages more on
the left, with some icon indicating that the message belongs somewhere
deeper? Something like:
">>> Blah subject"

Regards
Evgeni
