Remove subject linebreaks and tabs in thread_index

[mxmehl]

Some clients make linebreaks in the header's subject line when the title is long. For example:

Subject: [Feedback until 26 June]Online platform liability - project
    collaboration

In Astroid's thread_index, these line breaks or the tabs/spaces added cause an ugly space inside the subject line: http://i.imgur.com/KxVg8zi.png

Interestingly, in thrad_view the space isn't shown between the two words.

Is it present in the HTML source?

Yes, it seems to contain a tab, at least when I copy it to a text editor:

<div class="value">[Feedback until 26 June]Online platform liability - project  collaboration</div>

In that case I think it is gmime's reponsibility. I'm guessing the e-mail clients are not following the spec's?

Dunno but it seems to happen quite often, and I guess not caused by crappy Outlook but Free Software MUAs.

The line break seems to be normal but the addition of a tab is causing issues.

@mxmehl did you have a chance to test with those gmime functions?

[mxmehl]

No, not yet unfortunately...
