Bug 79172

Description of Problem:
In previous versions, the man page would be displayed with an appropriate number
of columns to suit the size of the terminal (I'm using an xterm set at 96x32
using X resources, but the same thing happens if I resize manually).


Version-Release number of selected component (if applicable):
[bill@fraser man]$ rpm -q man groff
man-1.5j-11
groff-1.18-6

How Reproducible:
View any man page in a xterm at other than 80 columns :)

Expected Results:
For the man page to be displayed at an appropriate width for the xterm.

Additional Information:
It appears that the command issued by man is trying to set the width as in
previous versions, but with the current version of groff it isn't working.  I
think this may be due to changes in an-old.tmac, but not absolutely sure. 
However altering the command to issue ".nr LL 96n" instead of ".ll 8.6i" works
fine ...

Result of "ps auxww" (trimmed):

If I rerun the same commands but change the echo command to ".nr LL 96n" it
works sort of OK (but the lines actually still wrap :() ,.... and amusingly if I
run man in a 80-column xterm I am finding lines wrapping occasionally(!) so
something is broken anyway ...
