Double loads, regex warnings, and cleanup, oh my!

[zenspider]

Hi hi hi... I'm poking at switching over to rogue and when ruby warnings are on (via ruby -w or $-w = true, or just plain rake spec w/ the right config), the project SPEWS. 331 lines worth to be clear...

Some (lots) of the output is ruby warning about duplicate regexp ranges and has pointed out a number of buggy regexps... not just duplicate ranges, but regexps that can't actually work right.

I'd like to clean it up (mostly done). Y'all interested?

Down to the following:

lib/rouge/lexers/julia.rb:255: warning: character class has duplicated range: /[\p{L}\p{Nl}\p{S}_][\p{Word}\p{S}\p{Po}!]*/

which might be smarter than me

Fixed by #2202. There are still some warnings left in Ruby 4.0+, but we have a bug open with Ruby about them: https://bugs.ruby-lang.org/issues/21870#change-116328
