Re: doc-strings: T vs t

[Richard Stallman]

     When a documentation string refers to a Lisp symbol, write it as it
    -would be printed (which usually means in lower case), with single-quotes
    -around it.  For example: @samp{`lambda'}.  There are two exceptions:
    -write @code{t} and @code{nil} without single-quotes.
    +would be printed (which usually means in lower case, even at the
    +beginning of sentences), with single-quotes around it.  For
    +example: @samp{`lambda'}.  There are two exceptions: write @code{t}
    +and @code{nil} without single-quotes.

I added more extensive info about this topic, so that change is not
needed.
