run-command: always set failed_errno in start_command
When we fail to fork, we set the failed_errno variable to the value of errno so it is not clobbered by later syscalls. However, we do so in a conditional, and it is hard to see later under what conditions the variable has a valid value. Instead of setting it only when fork fails, let's just always set it after forking. This is more obvious for human readers (as we are no longer setting it as a side effect of a strerror call), and it is more obvious to gcc, which no longer generates a spurious -Wuninitialized warning. It also happens to match what the WIN32 half of the #ifdef does. Signed-off-by: Jeff King <firstname.lastname@example.org> Signed-off-by: Junio C Hamano <email@example.com>
