>Description:
When the ps output is very wide, it gets truncated when outputting to a tty. That is fair and correct.
However, when piping to another process such as grep or less, the truncation still occurs and can lead to problems, especially when grepping for a specific items on a very wide output.
This patch will set the termwidth to UNLIMITED when stdout is not a tty. This is equilivant to adding ww to the command line.
It should be very low impact, ps w and ps ww (as well as ps outputting to a tty) still behave as expected.
Patch to follow in email - using web interface.
