Syntax error encountered while engraving a successfully updated Mutopia ly file

[Kenneth Wolcott]

Hi;

  I downloaded a Mutopia Greensleves ly source and successfully
converted it to 2.20.0 but get the following error when engraving:

././updated_greensleeves.ly:68:22: error: syntax error, unexpected
SCM_TOKEN, expecting ',' or '.' or '='
  top-markup-spacing
                     #'padding = #10

The output from convert was only the version numbers.

Please tell me how to fix this.

The engraving did succeed as there were pdf and midi files produced.

The paper section, below, is where the error occurs:

\paper {
  first-page-number = 2
  print-first-page-number = ##t
  top-markup-spacing #'padding = #10
  markup-system-spacing #'padding = #7
  system-system-spacing #'basic-distance = #14
}

Thanks,
Ken
