Addition to the texlive manual

[Karl Berry]

    Mit might be an idea to note that one need to re-login for changes
    in .profile to come into full effect (affect?)

effect is right :). Ok.

    Something similar probably ought to be added to the quick guide 

I was intentionally trying to avoid "educating" people about Unix basics
on TL's web pages, but ok, I added a sentence
https://tug.org/texlive/quickinstall.html about logout/login.

I find myself doubting that users will actually be reading that page so
carefully, but if it helps, good ... --thanks, karl.
