Use "&amp;" in place of "&".

I wouldn't.  If "&arg2" is something like "&section", you'll cause Netscape
3.x to get the URL wrong since it will interpret "&sect" as the section
sign.  So that you don't have to think, it's safer to always use "&amp;".

There's a widespread myth that browsers don't correctly interpret entities
in HREFs.  I've tested numerous browsers, and the only browser to fail on
this was Amaya 1.1c Beta.  Passing the test were Netscape 1.0N, Netscape
1.22, Netscape 2.02, Netscape 3.04, Netscape 4.04, MSIE 4.0, Opera 3.0b9b,
HotJava 1.1, NCSA Mosaic 3.0, Lynx 2.7, UdiWWW 1.2, and AOLpress 1.2.3.
Given the danger posed by Netscape 3.x's guessing, I think it's worth using
valid HTML over invalid HTML in this case.
