Many thanks for your time looking into this.

Indeed very interesting that it can be done inserting the comma

\version "2.19.26"

\markup \override #'(font-name . "Times New Roman,") "\\<==what?"

http://sourceforge.net/p/testlilyissues/issues/4591/

Meanwhile I've found
http://code.google.com/p/lilypond/issues/detail?id=699

Obviously it worked some time in the past, than not, than again ....

It's not clear to me why this happens. Is it a LilyPond-problem or
something at my part?
With 2.18.2 and 2.19.26 I'm on a 64-bit LINUX
Trying with a build from master, lilyDev (32bit Debian), I do get
substitute settings

If I try
\version "2.19.26"
\markup \override #'(font-name . "not existing font") "\\<==what?"

I do get substitute settings as well.
