Is efficiency really an issue?  I think the real reason is that it
would make it impossible for the callers to handle errors, if you do
not convert and let the error codepaths exit().

What is the logic behind this function sometimes clean the state,
and some other times do not, when it makes an error-return?  We see
above that "return 3" codepath leaves the state behind.

Either you forgot a necessary clean_state in "return 3" codepath,
or you forgot to document why the distinction exists in the in-code
comment for the function.  I cannot tell which, but I am leaning
towards guessing that it is the former.

Can you let it die yere?

Who owns "filename"?  The first "return 0" leaves it unfreed, and
when "goto done" is done, it is freed.

The above two may indicate that "perhaps 'retval + goto finish'
pattern?" is a really relevant suggestion for the earlier steps in
this series.

There were tons of "exit_if" that was converted to "if (res) return
res" above, instead of jumping here to cause clean_state to be
called.  I cannot tell if this new call to clean_state() is wrong,
or all the earlier "return res" should come here.  I am guessing the
latter.

That's an unbalanced comment.  You end the block with "*/" on its
own line, so you should start the block with "/*" on its own line.
There seems to be at least one more such comment in this patch but I
won't repeat.

"exit" meaning "call exit() to terminate the process", or something
else?  If the latter, don't say "exit", but say "return error".

Mental note.  The "autostart" in the original is gone.  Perhaps it
is done by next_check in this code, but we haven't seen that yet.

Doesn't it bother you that you have to write free(bad_ref)...fclose(fp)
repeatedly?

Doesn't it bother you that you have to write free(term_good) repeatedly?

Are you sure that the revision walking machinery is prepared to see
the argv[] and elements in it you have given to setup_revisions()
gets cleared before it starts doing the real work in
prepare_revision_walk()?  I am reasonably sure that the machinery
borrows strings like pathspec elements from the caller and expects
them to stay during revision traversal.

You seem to have acquired a habit of freeing and clearing things
early, which is bad.  Instead, make it a habit of free/clear at the
end, and make sure all error paths go through that central freeing
site.  That tends to future-proof your code better from leaking even
when later other people change it.

This one is still allowed to die, without clean_state?

This is really bad; you are blindly assuming that anything that
begins with "'" begins with "'" because "git-bisect.sh" sq-quoted
and it never directly came from the command line that _wanted_ to
give you something that begins with a "'".

I suspect that you should be able to dequote on the calling script
side.  Then all these ugliness would disappear.

Likewise.

In any case, I think a separate "const char *arg" that is an alias
to argv[i] in the loop is a very good idea to do from the very
beginning (i.e. should be done in a much much earlier patch in this
series).
