Fuzzy grep?

[Ralph Finch]

Is there something like grep, except it will (easlly) search an entire
file (not just line-by-line) for regexp's near each other? Ideally it
would rank hits by how much or how close they match, e.g.

fzgrep 'abc.*123' filename

would return hits not by line number but by how close abc & 123 are
found together.  Also it wouldn't matter what order the regexp's are.
