[OS X TeX] file names with spaces

[Gray, Gary L]

I have been happily creating LaTeX documents with spaces in the name for some time. After I ran a TeX Live Update this morning, they no longer typeset and I get:

This is pdfTeX, Version 3.14159265-2.6-1.40.20 (TeX Live 2019) (preloaded format=pdflatex)
 restricted \write18 enabled.
entering extended mode
(./name space.tex

./name space.tex:3: LaTeX Error: Missing \begin{document}.

Anyone know what changed in a recent update?
