/**
|

* Print a piece of text formatted, which means in a column with a

* left and a right margin. The lines are wrapped at whitspaces next
|
|
* to right margin. The function does not indent the first line, but
|
|
* only the following ones.
|
|
*
|
|
* Example:
|
|
* arg_print_formatted( fp, 0, 5, "Some text that doesn't fit." )
|
|
* will result in the following output:
|
|
*
|
|
* Some
|
|
* text
|
|
* that
|
|
* doesn'
|
|
* t fit.
|
|
*
|
|
* Too long lines will be wrapped in the middle of a word.
|
|
*
|
|
* arg_print_formatted( fp, 2, 7, "Some text that doesn't fit." )
|
|
* will result in the following output:
|
|
*
|
|
* Some
|
|
* text
|
|
* that
|
|
* doesn'
|
|
* t fit.
|
|
*
|
|
* As you see, the first line is not indented. This enables output of
|
|
* lines, which start in a line where output already happened.
