In addition to fix the bash incompatible issue of t6020, find another
issue when try to rewrite t5411 to compare raw command output.
Do the three later patches depend on the t6020 fix, or is this made
a 4-patch series only for the convenience of sending them out?
It's not like get_abbrev_oid() used in t6020 is defined in a common
part of the test library and later used by other tests (instead, the
patches duplicate this helper function into yet two more files).
