missing `export' option -p

missing `export' option -p

[Andrej Borsenkow]

While looking for field splitting case:

export name[=word]...
export -p
...
When -p is specified, export will write to the standard output the names and
values of all exported variables, in the following format:


"export %s=%s\n", <name>, <value>

'readonly -p' should also be supported under POSIX_BUILTINS

It also says <value> needs suitable quoting.  We already do this in a lot
of other places, it's surprising we haven't thought of doing it here.
