   (For Lua 5.1)

   Modified slightly by RiciLake to avoid the unnecessary table traversal in tablecount()

   Formats tables with cycles recursively to any depth.
   The output is returned as a string.
   References to other tables are shown as values.
   Self references are indicated.

   The string returned is "Lua code", which can be procesed
   (in the case in which indent is composed by spaces or "--").
   Userdata and function keys and values are shown as strings,
   which logically are exactly not equivalent to the original code.

   This routine can serve for pretty formating tables with
   proper indentations, apart from printing them:

      print(table.show(t, "t"))   -- a typical use

   Heavily based on "Saving tables with cycles", PIL2, p. 113.

   Arguments:
      t is the table.
      name is the name of the table (optional)
      indent is a first indentation (optional).
