look -d ignores white space (with fix)

[Rob McMahon]

Look's -d flag disagrees with both sort's and the manual on the treatment of
white space, which makes it error-prone when searching the output from sort.
The manual says it ignores everything except letters, digits, space and tab,
in fact it ignores space and tab too.

Fix:
