Re: [Wget-dev] wget2 | Implementation of -I/-X options (!383)

[Tim Rühsen]

The original behavior is limited in what you can specify with -I and -X.

We decided to make it more powerful, when we read -X / -I from left to right 
(same as your implementation checking from right to left and stop at the first 
match).

So we can have exceptions and exceptions from exceptions, etc...

Your example:
```
--exclude-directories=/firstdir --include-directories=/*,/*/pub
```
It reads "Download all, but no stuff from /firstdir except stuff from 
/firstdir/pub".

Turning it around:
```
 --include-directories=/*,/*/pub --exclude-directories=/firstdir
```
It reads "Just download from / (which means ALL and already includes /*/pub) 
except stuff from /firstdir"

So to also download stuff from /firstdir/pub, it must be
```
 --include-directories=/* --exclude-directories=/firstdir 
--include-directories=/firstdir/pub
```

You can leave away the first `--include-directories=/*` to get the same result.

IMO this is logical, easy to memorize, powerful and easy to explain.
