I'm not sure if Debian 10 is actual for the current master. But, if this is the case,
i suggest a patch, since the test will not work under this OS.
The thing is that, Debian 10 will backslash curly braces and the question mark and
TAB completion will lead to the string like that:

\echo :\{\?VERBOSITY\}

instead of expected:

\echo :{?VERBOSITY}

The patch attached fix the 010_tab_completion.pl test in the same way like [1].

With the best regards,
