Attached is a diff that takes care of that. Basically, the user can
specify a format that looks like "%f\t%U\t%A" to get the files name, the
username of the owner, and the last access time seperated by tabs
followed by a new line. All of the supported format specifiers are
documented in the man page. I looked around for another version of stat
that does this but could not locate one; therefore the format specifiers
are what made sense to me. There is also limited support for C-style
escape sequences (no \nnn).
Have a nice day!
