Try
git shortlog --no-merges -40
to learn how commits are typically titled. And then imagine this
patch makes into our codebase and appear in the output.
Can you tell what this commit is about from that single line title?
No. You wouldn't even know that it is only touching bisect.h and
nothing else.
What do your readers want "shortlog" output to tell them about your
commit? What are the most important thing (other than giving you an
excuse to say "I have completed a microproject and now I am eligible
to apply to GSoC" ;-)? Your proposed commit log message, especially
its title, must be written to help future readers of the project
history.
Perhaps
bisect.h: make flags field in rev_list_info unsigned
would help them better.
> Unsigned int is a closer representation of bitflags rather than signed int that uses 1 special bit for sign.This shouldn't make much difference because rev_list_info.flags uses only 2 bits(BISECT_SHOW_ALL and REV_LIST_QUIET)
Overlong lines, without space after full-stop before the second
sentence, without full-stop at the end of the sentence.

Have you checked how this field is used? For example, there is this
line somewhere in rev-list.c
int cnt, flags = info->flags;
and the reason why the code copies the value to a local variable
"flags" must be because it is going to use it, just like it and
other codepaths use info->flags, no? It makes the code inconsistent
by leaving the local variable a signed int, I suspect.
