Disable terminal protocols before expanding wildcards

Commit 29f2da8d1 (Toggle terminal protocols lazily, 2024-05-16) made it so
the wildcard expansion in "echo **" (in a large directory tree) can't be
canceled with ctrl-c.  Fix this by disabling terminal protocols already at
expansion time (not waiting until execution).
