Yahoo Finance error

When searching for Mahindra and Mahindra. (The guys who make the jeep that I must buy)
http://finance.yahoo.com/lookup?s=mahindra&t=S&m=ALL

I get to this page
http://finance.yahoo.com/q?s=M%26M.NS
This works fine. Howerver, when I click on technical analysis, it takes me to

http://finance.yahoo.com/q/ta?s=M&M.NS
Here the "&" messes up and gives "not a valid ticker symbol, since the brower takes this in the URL to go daft.

Correct page should be
http://finance.yahoo.com/q/ta?s=M%26M.NS
which works fine.
Problem is not restricted to Yahoo.... Happens even on Buzzingstocks.
And you guys thought all I do these days is post pictures.
