Description of problem:
Very long pieces of email overflow the short used to hold the message length.
When
displaying available messages the message length will often be negative when
this
happens. Then since the message appears so "small", mailx does not use a pager
to display the message but just dumps it to the screen.

Version-Release number of selected component (if applicable):


How reproducible:
Always

Steps to Reproduce:
1. Create a mailbox with a message with a number of body lines greater than a
short.
2. Open that mailbox with mailx.
3. Try to read that message.
	

Actual Results:  Huge message gets dumped to the screen.

Expected Results:  Huge message should be displayed with a pager.

Additional info:

I've got a bunch of mods now to mailx, so diff gives me a lot of output. (I am
also using a mailx from an earlier version of RedHat, but I did just verify that
this still exists in my new RH7.1 install.) I believe this patch will completely
fix
the problem:
