But what if the user enters such a regexp as "abc|xyz",
then it will be composed into such command:
grep -oE '.{0,20}abc|xyz.{0,20}'
that matches either 20 characters before "abc", or 20 characters
after "xyz". Then needs to add parentheses:
grep -oE '.{0,20}(abc|xyz).{0,20}'
What is worse is that the whole match is highlighted,
including 20 characters before and after the real match.
So it seems this solution is not perfect.
