zen_image: Why the extra spaces in the title= attribute?

Is there a reason why the zen_image function (in /includes/functions/html_output.php) adds a space before and after the alt-text when creating the title= attribute for the <img> tag?

    if (zen_not_null($alt)) {
      $image .= ' title=" ' . zen_output_string($alt) . ' "';
    }

Readability?   
Remnants of someone trying to figure out what quotes needed to go where?  

To avoid accidental concatenation of elements? (especially for screen readers)   

Other than these, I can't think of any functional reason for it.

Exactly!

Been there since 2004 in v1.1.4 ... maybe was needed way back when and never changed ... :lookaroun

Thanks, Ajeh! I'll get them gone ...

The user agent spec says they should stripped (although it seems they do not), and Total Validator flags them as an error.

Got bored and hunted through old code ... this was actually inherited from osC a bazillion years ago and never changed ...

ZC156: still exists in several places.

fixed in ZC157. Breathe easy again.
