> 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.
> This issue was created based on discussion in the following two mailing list threads.
>  * [egrep usage - 1.3.4|]
>  * [Re: egrep usage - 1.3.4|]
> Based on this discussion, -g and --global seem like good candidates for the options to
add to egrep.
