Couldn't it just use ';' isntead of & or & - no url (un?)escaping

That's a CGI.pm weirdness, and can't be relied upon. Plus, I'm sure
there will be other characters that need escaping in the url sometimes..

B.2.2 Ampersands in URI attribute values
The URI that is constructed when a form is submitted may be used as an
anchor-style link (e.g., the href attribute for the A element).
Unfortunately, the use of the "&" character to separate form fields
interacts with its use in SGML attribute values to delimit character
entity references. For example, to use the URI "http://host/?x=1&y=2";
as a linking URI, it must be written <A
href="http://host/?x=1&y=2";> or <A
href="http://host/?x=1&y=2";>.
We recommend that HTTP server implementors, and in particular, CGI
implementors support the use of ";" in place of "&" to save authors
the trouble of escaping "&" characters in this manner.
