The options -q --unmerged (which are implicitly passed by "git status")
are not only to suppress verbosity:
The git-update-index man page has to say for these options:

: the default behavior is to error out. This option makes
: git update-index continue anyway.

and if I understood the git source code correctly, without
these options git will indeed break some loops early in the
"error" case, i.e. it will perhaps not do a full update of
the index in the "error" case.
