If NEWNAME names a directory, copy FILE there.
-Signals a `file-already-exists' error if file NEWNAME already exists,
-unless a third argument OK-IF-ALREADY-EXISTS is supplied and non-nil.

+This function always sets the file modes of the output file to match
+the input file.
+
+The optional third argument OK-IF-ALREADY-EXISTS specifies what to do
+if file NEWNAME already exists. If OK-IF-ALREADY-EXISTS is nil, we
+signal a `file-already-exists' error without overwriting. If
+OK-IF-ALREADY-EXISTS is a number, we request confirmation from the user
+about overwriting; this is what happens in interactive use with M-x.
+Any other value for OK-IF-ALREADY-EXISTS means to overwrite the
+existing file.
Fourth arg KEEP-TIME non-nil means give the output file the same
last-modified time as the old one. (This works on only some systems.)
A prefix arg makes KEEP-TIME non-nil.
-The optional fifth arg MUSTBENEW, if non-nil, insists on a check
-for an existing file with the same name. If MUSTBENEW is `excl',
-that means to get an error if the file already exists; never overwrite.
-If MUSTBENEW is neither nil nor `excl', that means ask for
-confirmation before overwriting, but do go ahead and overwrite the file
-if the user confirms.
