This is the first in a planned series of patch series aimed at

Doxygen eats the newline in the first comment, making it harder to read.
Join the lines and add a comma, so source and documentation are equally

Doxygen only associates the second comment with cust_dec.
The comments for cust_dec and cust_tab make perfect sense without it,
so downgrade i
Doxygen only associates this comment with "pts_correction_num_faulty_pts",
