--indicator-style=directory equivalent to -p.
When POSIXLY_CORRECT is set, "fold file -3" is now equivalent to
"fold file ./-3", not the obviously-erroneous "fold file ./-w3".
+ ls changes:
+
+ -p now appends '/' only to directories; it is equivalent to the
+ new option --indicator-style=directory. Use --file-type or
+ --indicator-style=file-type to get -p's old behavior.
+
nohup changes:
nohup now ignores the umask when creating nohup.out.
