Re: [PATCH] use write_str_in_full helper to avoid literal string lengths

These days, compilers are good enough that strlen("literal")
imposes no run-time cost.

Transformed via this:

    perl -pi -e \
        's/write_in_full\((.*?), (".*?"), \d+\)/write_str_in_full($1, $2)/'\
      $(git grep -l 'write_in_full.*"')

Thanks.  I agree with the reasoning you wrote outside the proposed log
message.

We usually do not write these bullet points (iow, we are not GNU) in our
log message.  The names of the functions, call sites and files that are
involved are something anybody can see from the patch text,

I think the GNU convention was useful back when we were trapped in a
system with non-atomic commits, where it was very hard to see what files
were affected in a single logical changeset (i.e. CVS).

Luckily, we graduated those dark ages.

Instead, we prefer to have justifications (and methods), like what you
wrote at the beginning of your message.  These are not something people
can find in the patch text and they deserve to be recorded in the commit.
