* src/pr.c
(main): Redefine options -s, -w to be POSIX compliant; introduce
new options -J, -S, -W to disentangle -s and -w when used together
with the three column options;
(add_line_number): Make POSIX compliant; use default number
separator TAB with single column output.
(add_line_number): Make POSIX compliant; with multicolumn output
now prefer `text columns of equal width' rather than a consequent
use of `default n-separator TAB'.
(add_line_number): Change line number cut-off from lower-oder to
higher-oder digit to avoid loss of information; no consequent
handling exists in different utilities and other UNIXes.
(char_to_clump): Expand input text tabs to 8 spaces, if
input_tab_char doesn't equal TAB (adapted to other UNIXes).
(usage): Update POSIX compliant options -s, -w; add new options -J,
-S, -W.
(main): Update the source internal documentation.
