Function is_missing_file_error

git-compat-util.h:1062–1065

* Our code often opens a path to an optional file, to work on its * contents when we can successfully open it. We can ignore a failure * to open if such an optional file does not exist, but we do want to * report a failure in opening for other reasons (e.g. we got an I/O * error, or the file is there, but we lack the permission to open). * * Call this function after seeing an error from ope

 * see if the errno indicates a missing file that we can safely ignore.
