That's the browser (whichever one you're using) attempting to compensate for
your badly encoded URL. This is not behaviour you should rely on.
In fact I don't know what browser you're using, because IE, Firefox and Opera
attempt to correct the invalid URL by converting the space to %20, not +.
Putting that source through an HTML validator (HTML Tidy) produces:
line 1 column 1 - Warning: <a> escaping malformed URI reference
error: <...> escaping malformed URI reference
Cause:
An URI contains non-authorized characters. Or the quotes around the URI are not
closed.
Solution:
Correct the URI.
Samples:
error: <a> escaping malformed URI reference
BAD <a href="http://www.mozilla.org/one space.html">space</a>
GOOD <a href="http://www.mozilla.org/one%20space.html">space</a>
GOOD <a href="http://www.mozilla.org/one+space.html">space</a>
BAD <a href="http://www.w3c.org>w3c</a>
GOOD <a href="http://www.w3c.org">w3c</a>
For the first example, a space should not be contained in URL. (Even if it
works in all browsers...). This is described in detail in the RFC1738 (Look for
Unsafe)
