Frescobaldi language problem

[John Karl]

I've have apparently reset Frescobaldi's language selection for its 
"Lilypond log" output from English to German and have been unable to 
undo this.  I think this probably happened when I was playing around 
with a lilypond-user request from someone in Germany.  I'm running 
Frescobaldi 2.19.0 on a mac running Osx 10.12.6.

To illustrate, I have the following in a file called lang.ly:

\version "2.19.82"
{ c d e f }

So, if I tell Frescobaldi to compile the file lang.ly, its "Lilypond 
log" output begins:

    Starting lilypond 2.19.82 [lang.ly]...

    "Users/pat/Downloads/lang.ly" wird verarbeitet

    Analysieren...

    Interpretation der Musik...

    usw.


whereas if from a terminal I do:  "lilypond lang.ly"

the terminal output begins:

    GNU LilyPond 2.19.82
    Processing `lang.ly'
    Parsing...
    Interpreting music...

    etc.


I have dropped and restarted Frescobaldi with no effect on this 
problem.  I have looked for language specifications in the Frescobaldii 
preferences, unsuccessfully.


How do I get back to English Frescobaldi output?
