# Some refs (refs/bisect/*, pseudorefs) are kept per worktree, so they should
# only appear in the for-each-reflog output if it is called from the correct
# worktree, which is exercised in this test. This test is poorly written (and
# therefore marked REFFILES) for mulitple reasons: 1) it creates invalidly
# formatted log entres. 2) it uses direct FS access for creating the reflogs. 3)
# PSEUDO-WT and refs/bisect/random do not create reflogs by default, so it is
# not testing a realistic scenario.
