bug#21470: 25.0.50; (elisp) Font and Color Parameters - `alpha' entry

[Drew Adams]

The text says:

   The =A1=AEalpha=A1=AF frame parameter can also be a cons cell =A1=AE(=
=A1=AEactive=A1=AF .
   =A1=AEinactive=A1=AF)=A1=AF, where =A1=AEactive=A1=AF is the opacity o=
f the frame when it is
   selected, and =A1=AEinactive=A1=AF is the opacity when it is not selec=
ted.

Getting rid of the buggy treatment of curly quotes manually (I will
file a separate bug report about that), the text reads as follows:

   The 'alpha' frame parameter can also be a cons cell '('active' .
   'inactive')', where 'active' is the opacity of the frame when it is
   selected, and 'inactive' is the opacity when it is not selected.

Following Emacs conventions, it should say instead:

   The 'alpha' frame parameter can also be a cons cell (ACTIVE .
   INACTIVE), where ACTIVE is the opacity of the frame when it is
   selected, and INACTIVE is the opacity when it is not selected.

Or just:

     Parameter 'alpha' can also be a cons cell, (ACTIVE . INACTIVE),
     where ACTIVE is the opacity of the frame when selected, and
     INACTIVE is the opacity otherwise.
