tests: expand flags to long form in test-largefiles-update.t I spent some time confused by this test. I'm pretty sure that this line intends to be cleaning the dirstate, not checking that it's clean before updating: the preceding #if block leaves the dirstate clean in the noexec case, and dirty in the exec case, so we can't expect consistent behavior across that platform variation. A subsequent patch will modify this command to use --clean instead of --check. I'll elaborate in that patch about the hypothetical bug here.

# Dummy extension that adds a delay after acquiring a lock.
#
# This extension can be used to test race conditions between lock acquisition.
