NSSearchField remaining issues

[Doug Simons]

Yesterday I updated NSSearchFieldCell.m (r31911) to fix a number of issues with 
things not displaying quite right and with the search menu in particular. 
Mostly search fields are now working much better, with behavior that more 
closely matches Cocoa.

There are a couple of little things left that I didn't manage to track down, 
though, so if anyone else has an idea or cares to take a look that would be 
much appreciated. Specifically:

1. Clicking in the search field when it contains text but is not already being 
edited causes the insertion point to be placed in front of the text rather than 
at the click location. I tried to trace this problem in the debugger but there 
are lots of methods involved. It seems to basically be calling the same code as 
ordinary text fields, but it doesn't work the same for search fields for some 
reason.

2. On Windows, using the WinUX theme, the search menu items don't highlight as 
you drag the mouse over the menu. Other popup and pulldown menus are 
highlighting fine, and I think this is calling the same underlying code in a 
similar way (although I didn't dig into it extensively). So if anyone has an 
idea what might be missing here that would be helpful.

Thanks,
