Of course. I wasn't clear at all. The goal is to enter a regular expression
and then highlight all matching strings in a text (like Editor.ShowString()
does for fixed strings).

One may also replace all matches by another string (currently not containing
submatches of the original expression because it was just a POC for an
article about gb.pcre). I'd just leave this task to an invocation of 'sed'.

BTW, I finished the thing yesterday and the attached code may show better
what I was trying to explain.

Tobi
