[tex-live] 3.4.4 System font configuration for XeTEX and LuaTEX

[jfbu]

Hi

> On Windows and Mac OS X, fonts shipped with TEX Live are made
  available to XeTEX automatically.

in section 3.4.4 System font configuration for XeTEX and LuaTEX of
the The TEX Live Guide—2016.

I wonder about the validity of that assertion about Mac OS X. Does
MacTeX do anything special which is new ? because in recent years
I don't think that was the case. Indeed, the common advice on the
Mac OS X mailing list is to *copy* manually all fonts one wishes
to use from the TeXLive tree to the user $HOME/Library/Fonts
repertory for XeTeX visibility.

Else one must use filenames, or fontspec with ExternalLocation
key.
