Ok, but you don't say how, for example, the following should be considered:

aaa LEC foo bar baz ulty abc def LEC yyy xxx ulty

is that two instances of your pattern, or a single one, or it can never 
happen?

I don't know what textwrangler is, but grep itself is a tool that only does 
pattern matching, ie print lines matching a pattern. No text replacement is 
possible with grep alone.
