shouldn't http::formatQuery be slightly modified



I recently checked the site I maintain (cgi-scripts based on tcl) with
the W3C html-validator at http://validator.w3.org/ and discovered that
the validator warns on URI's that contain unescaped & (ampersands) like
in <scriptname>?<par1>=<val1>&<par2>=<val2>... the validator suggests to
use &amp; instead of &. FF1.5 and IE6 interpret these correct.
As I'm using http::formatQuery to insert the Links into the pages the
easiest way was to modify the http.tcl file supplied with core tcl.
Is there any reason to not making this change to the core ?
Shall I file a TIP ? Even for adding only 4 chars to the body of
http::formatQuery ?
