> Egrep and RegExfilter use java Matcher.match() which only returns true if the expression
matches the entire string.  Matcher.find() can detect when an expression matches a subsequence
of the string.  Need an option to use find in egrep and RegexFilter.

> Based on this discussion, -g and --global seem like good candidates for the options to
add to egrep.
