Re: [PATCH] setup.c: use die_errno() when chdir() system call fails

The usual way to compose a log message (i.e., what the readers would have seen above that three-dash line we see) of this project is to
- Give an observation on how the current system works in the
present tense (so no need to say "Currently X is Y", or
"Previously X was Y" to describe the state before your change;
just "X is Y" is enough), and discuss what you perceive as a
problem in it.
- Propose a solution (optional---often, problem description
trivially leads to an obvious solution in reader's minds).
- Give commands to somebody editing the codebase to "make it so",
instead of saying "This commit does X".
in this order. And then to conclude the message, add your sign-off (see Documentation/SubmittingPatches:[[sign-off]]).

The changes are trivially correct, in that you call die_errno() immediately after seeing chdir() fail (which means there is no other potential failures that can contaminate errno---what your die_errno() will report cannot be anything but what we got from chdir()).
