Exception when formatting a selection at the start of the file.

[Arvid Norlander]

Using R2019B, I get the following when using the "format selection" functionality, if the selection starts anywhere in the first line of the editor window:

Undefined function or variable 'lineBeforePosition'.

Error in MBeautify.formatEditorSelection (line 137)
            expandedSelection = [lineBeforePosition(1), 1, expandedSelection(3), Inf];
 
137             expandedSelection = [lineBeforePosition(1), 1, expandedSelection(3), Inf];
