Folks,
consider the following example.
======================================================================
\input texinfo.tex
@macro q{TEXT}
@quoteleft{}\TEXT\@quoteright{}
@end macro
@cindex @q{accent} articulation
text
@printindex cp
@bye
======================================================================
Attached you can find the tex output using texinfo.tex from
2019-02-16.14 and 2020-05-22.11; as you can see, the @q macro
is no longer correctly expanded in the new version.
This is definitely a bug.
