[SEToolkit-developer] Enhancement: Upgrade expression operator from Basic to Extended Regular Expressions.

[Jon C. <can...@gm...>]

I've had several occasions where basic RE just couldn't do what I
needed and I've longed for full extended REs.  That was my initial
impetus to getting the SE Toolkit environment to build.  What are
others thoughts on using regcomp/regexec over compile/step to enable
extended regular expressions.  I've got a patch that implements this.
