It was not documented, so I did not add an entry in COMPAT.

One may use one of the old standard documented functions ( output(), etc ) or

  void brute(GEN g, char f, long d)

[ corresponds to old bruteall(g, f, d, 1 ) ] for fine tuning.

Or, much better,

  void gen_output(GEN g, pariout_t *T)

where T specifies everything the output routine might need.

  T = NULL: default output as specified by current values of PARI defaults

( GP_DATA->fmt if set, global DFLT_OUTPUT otherwise ), otherwise

  typedef struct {
    char format; /* e,f,g */
    long fieldw; /* 0 (ignored) or field width */
    long sigd;   /* -1 (all) or number of significant digits printed */
    int sp;      /* 0 = suppress whitespace from output */
    int prettyp; /* output style: raw, prettyprint, etc */
    int TeXstyle;
    int initial; /* private */
  } pariout_t;

A specialized output routine might look like this:

  pariout_t t;
  t = GP_DATA? GP_DATA->fmt: DFLT_OUTPUT; /* get global defaults. Copy */
  t.xxx = yyy; /* change a few relevant fields */
  ...
  gen_output(g, &t);

I will probably document this.
