bug#15371: 24.3.50; Index the `default' face in Elisp manual

[Drew Adams]

1. Subject line says it all.  Please index face `default'.  It is the
most important face, and the default face is an important concept when
trying to understand faces in general.

2. There are also buffer-local displays of face `default'.  These too
should be indexed.

3. This text in node `Face Remapping' is misleading, and should be fixed: 

  ";; Increase the size of the `default' face by 50%:"

The size of the face is not increased at all here.  All that is happening
is face remapping, so face `default' gets displayed larger in the current
buffer.  The face itself is a global thing, and its size is not changed
by this operation.
