In cmd_bisect__helper() function, there would be a bug
if an invalid or no subcommand was passed.return error()
should be replaced by BUG() in that case.

Following 'enum bisect_error' vocabulary, return variable 'res' is
always non-positive.
Let's use '-res' instead of 'abs(res)' to make the code clearer.

Let's refactor code adding a new `write_in_file()` function
that opens a file for writing a message and closes it and a
wrapper for writting mode.
This helper will be used in later steps and makes the code
simpler and easier to understand.

Should this maybe just be BUG()?

This isn't quite right - vfprintf() returns a negative value on
error, or the number of characters printed on success. Zero is
technically OK (if the format and arguments ended up empty).

How can a string "mode" be equal to "a" and "w" at the same time?
The only caller you have at this point passes "w" and nothing else.
It may be easier to follow the evolution of the code in the series
if you left this as
if (strcmp(mode, "w"))
BUG("write-in-file does not support '%s' mode", mode);
at this step, and turned it into
if (strcmp(mode, "w") && strcmp(mode, "a"))
BUG("write-in-file does not support '%s' mode", mode);
in the step where a caller starts to call it for appending.

Shouldn't this check for negative return? It is not an error to
pass format that ends up writing nothing, but any error should be
reported by returning a negative value from vfprintf(), I would
think.
(a tip for a student/mentee)
Any time you call a system library you are not familiar with,
make it a habit to always consult its manual page for return
values and its error reporting convention.

Shouldn't this now be just
return res;
as all the error codepaths that can reach here are returning error()
or error_errno() after this patch?

Reimplement the `bisect_autostart()` shell function in C and add the
C implementation from `bisect_next()` which was previously left
uncovered.
Add `--bisect-autostart` subcommand to be called from git-bisect.sh.
Using `--bisect-autostart` subcommand is a temporary measure to port
the shell function to C so as to use the existing test suite. As more
functions are ported, this subcommand will be retired and
bisect_autostart() will be called directly by `bisect_state()`.

Reimplement the `bisect_next()` and the `bisect_auto_next()` shell functions
in C and add the subcommands to `git bisect--helper` to call them from
git-bisect.sh .
bisect_auto_next() function returns an enum bisect_error type as whole
`git bisect` can exit with an error code when bisect_next() does.
Using `--bisect-next` and `--bisect-auto-next` subcommands is a
temporary measure to port shell function to C so as to use the existing
test suite. As more functions are ported, `--bisect-auto-next`
subcommand will be retired and will be called by some other methods.

Add the subcommand to `git bisect--helper` and call it from
git-bisect.sh.
With the conversion of `bisect_auto_next()` from shell to C in a
previous commit, `bisect_start()` can now be fully ported to C.
So let's complete the `--bisect-start` subcommand of
`git bisect--helper` so that it fully implements `bisect_start()`,
and let's use this subcommand in `git-bisect.sh` instead of
`bisect_start()`.

The `--bisect-clean-state` subcommand is no longer used from the
git-bisect.sh shell script. Instead the function
`bisect_clean_state()` is directly called from the C
implementation.

Reimplement the `bisect_state()` shell functions in C and also add a
subcommand `--bisect-state` to `git-bisect--helper` to call them from
git-bisect.sh .
Using `--bisect-state` subcommand is a temporary measure to port shell
function to C so as to use the existing test suite. As more functions
are ported, this subcommand will be retired and will be called by some
other methods.
`bisect_head()` is only called from `bisect_state()`, thus it is not
required to introduce another subcommand.

Funny indentation at the beginning, and worse yet, triggers an error
with -Werror=missing-prototypes.
What is the relationship between this one and the similarly-named on
in bisect.c?
