[BUG] Git 2.42.0-rc2 t1092.57 script error

Hi Team,

I'm getting the following error when running t1092.57 in Git 2.42.0-rc2 on NonStop ia64:

+ ensure_not_expanded status
test_region[8]: test: argument expected
grep: ensure_full_index: No such file or directory
error: last command exited with $?=1
not ok 57 - sparse-index is not expanded

Any suggestions?
