As to emptying the nofind variable, I've always just done something like nofind= (that's just an empty = ). "unset" is probably even better...
I believe you use "trap" to catch a ctrl-c in bash, but I've never experimented with it. See, e.g., http://tldp.org/LDP/Bash-Beginners-Guide/html/sect_12_02.html I understand your motivation, but might your wife not be just as impressed if you did the same thing in fewer lines and easier code by using ruby or python? Python has standard libraries to handle getting and parsing (and logging in, and managing cookies) pages by URL, and I was told that ruby did too...
