[edit] First paragraph

I have added an introductory paragraph before the history section, explaining by means of example the basic regex operations. This used to be buried in the formal language theory section, which makes it opaque to a lay audience. This led to some minor edits in the formal language section.

[edit] Removed Regular expressions used when editing Wikipedia

Removed Regular expressions used when editing Wikipedia to Wikipedia:Avoid self-references. --Anon.

[edit] Missing information about locale

The section about Unicode should be preceded with something about locale and collating. Those issues rise before introducing unicode charachters.

[edit] remove regexlib.com

regexlib.com is totally wrong here, they have a crappy design and no good content, why is it still listed?

[edit] History of the Henry Spencer regexp engine(s)

The reference to Henry Spencer and Tcl is a bit off. Tcl actually adopted Henry Spencers regexp engine twice, once for the pre-8.1 Tcl versions (which is the same Version Perl is based on), and then later for the Unicode supporting Tcl 8.1+ versions a new, unicode able regexp engine which was written by Henry Spencer under contract for Scriptics... (around 1996 or 1997) This new regexp engine is also used in PostgreSQL.
