Windows 2000 with cygwin
>Description:
Sending a large file via command line causes a segmentation fault
>How-To-Repeat:
tail -3000 somefile | mutt -s "Sending something"  user@xxxxxxxxxxxxx
>Fix:
The crash happens at the mutt_pager function.
The function uses curses "LINES".
However, since we are running in batch mode, curses was not initialized, and 
LINES evaluates to zero.
A lot of bad things happen; e.g. lineInfo is allocated with zero bytes, and is 
thus a NULL pointer
