Cause:
Sudo word wrapping feature caused output to be wrapped at terminal width boundary even in output that was piped to an other command.
Consequence:
When piped to grep for example, the matching line could be displayed incomplete due to the output being wrapped by sudo before passing it to grep.
Fix:
Code was added to sudo to detect whether the output is a pipe and disabling the word wrapping feature if that's the case.
Result:
Sudo doesn't wrap the output if it goes to a pipe. Greping output from sudo works as expected.
