If you call this reply_strbuf, and introduce "const char *reply",

... assign "reply = reply_strbuf.buf" here, you do not have to
change anything below.

And we shouldn't sneak an unrelated change like this into a patch
whose purpose is to allow reading from the standard input instead of
always from "/dev/tty".
As I explained earlier, git_read_line_interactively() is usable only
when we know that the standard input is *not* used for the data we
are operating on and is available to be used for simulating
interactive input. Since "git am -i" never reads the mailbox from
the standard input, the use of the helper here is acceptable.

The use of this helper here is also OK as the standard input to "git
bisect" is available for simulating interactive input.

It may make sense to have a thin wrapper around this pattern, e.g.
static int ask_yesno(const char *question)
{
struct strbuf answer = STRBUF_INIT;
printf("%s [Y/n]? ", question);
git_read_line_interactively(&answer);
return !(answer.buf[0] == 'N' || answer.buf[0] == 'n');
}
so that the above caller can become
return ask_yesno(_("Are you sure")) ? 0 : -1;
and ...

... this caller can become
if (ask_yesno(_("Do you want me to do it for you")))
res = bisect_start(terms, empty_strvec, 0);
else
res = -1;
Thanks.
