Hi Junio,

if I put on my head the implementor's hat, I would agree with you: that command
after all behaves as implemented.
However, if I put the user's hat I would reason differently. What I
need are predictable
commands, and that by all means is not. This because the time at which a command
is executed is not predictable (more precisely, the statement in it
that reads the system
calendar). So, even if an implementor thinks that this behavior is
reliable, a user
thinks that it is not predictable. Actually, I called that command
from within a script,
and thus I could not count on it being executed within 1 second from
the last commit.
Read also the paragraph in the man page that describes it:

"Usually recording a commit that has the exact same tree as its sole
parent commit is a mistake, and the command prevents you from making
such a commit. This option bypasses the safety, and is primarily for
use by foreign SCM interface scripts."

I cannot find any clue in it that lets me know that is does not create
a commit if the time is
within the same second as the other commit.

My suggestion is either to include a sleep in the command so as to
guarantee that a commit
is created, or to remove the option.
