basic/extract-word,man: clarify "correction" of invalid escapes

Our warning message was misleading, because we wouldn't "correct" anything,
we'd just ignore unkown escapes. Update the message.

Also, print just the extracted word (which contains the offending sequences) in
the message, instead of the whole line.

Fixes #4697.
