grib_filter/bufr_filter: How do I control the format of array printing?

Step-by-step guide

One can add several 'modifiers' to a key in square brackets to control number of columns, separator string and format:

[key!c%F'S']
 c -> number of columns
 F -> C-style formatting
 S -> separator string

1. Examples:

   [latitude!11] -> print array using 11 columns [latitude','] -> print array with entries separated by a comma [latitude%.5f] -> print real numbers with 5 decimal places

   
   

2. Note: to print all the values on one line, set the number of columns to 0 (zero).
