[PATCH] [PATCH] commit.c: Replace starts_with() with skip_prefix()
In record_author_date() :
Replace buf + strlen(author ) by skip_prefix(), which is
saved in a new const char variable indent_line.
In parse_signed_commit() :
Replace line + gpg_sig_header_len by skip_prefix(), which
is saved in a new const char variable indent_line.
In parse_gpg_output() :
Replace buf + strlen(sigcheck_gpg_status[i].check + 1) by
skip_prefix(), which is saved in already available
variable found.

Hey Eric,
As per your suggestion in the previous mail :
http://article.gmane.org/gmane.comp.version-control.git/243316
I have made necessary changes:
1. Better Naming of variables as per suggestion
2. Proper replacement of skip_prefix() over starts_with() .

Hi,
I was attempting the same microproject so I thought I would share some
points that were told to me earlier .The mail subject should have a
increasing order of submission numbers for each revision(for example here it
should be [PATCH v2]).
Also write the superfluous stuff which you have written in the bottom
after ---(the three dashes after the signed off statement) .
In the parse_signed_commit() function, gpg_sig_header_len and gpg_sig_header
variables are precomputed outside of the function, and also Junio said to
prefer starts_with(), whenever skip_prefix() advantages are not so important
in the context.So the replace may not be so advantageous ,I may be wrong in
this case.
Cheers,
Tanay Abhra.

Re: [PATCH] [PATCH] commit.c: Replace starts_with() with skip_prefix()
Hey Tanay,
1. Yes just getting used to git send-email now, should follow that from now
2. I thought it shouldn't be a part of the commit, so i put it after
the last ---
3. I did have a thought on your lines also , but concluded to it being
more advantageous, you might be right though
Nice to hear from you.
Thanks

Re: [PATCH] [PATCH] commit.c: Replace starts_with() with skip_prefix()
Thanks for the resend. Etiquette on this list is to cc: people who
commented on previous versions of the submission. As Tanay already
mentioned, use [PATCH vN] in the subject where N is the version number
of this attempt. The -v option of git format-email can help.
More below.

It's not necessary to explain in prose what the patch itself already
states more concisely and precisely. All of this text should be
dropped from the commit message. Instead, explain the purpose of the
patch, the problem it solves, etc. Please read the (2) Describe your
changes well section of Documentation/SubmittingPatches to get an
idea of what sort of information to include in the commit message.
A better commit message should say something about how the affected
functions want to know not only if the string has a prefix, but also
the text following the prefix, and that skip_prefix() can provide both
pieces of information.

To understand why, look at how much scrolling up and down a person has

'found' is being computed again here, even though you already computed
it just above via skip_prefix(). This seems pretty wasteful.
Ignore this objection. I must have misread the code as I was composing
the email.
