Could you please add numerical ordering by title to [[inline|plugins/inline]]
plugin? Now I can do only alphabetical order by title, but sometime it's not enough.
> Implemented, see [[natural_sorting]] [[!tag done]] --[[Joey]]
BTW, it seems that ordering by title is rather ordering by filename of page.
For me "title" means title of page I can set using `title` parameter
of [[meta|plugins/meta]] plugin :)
Why do I need that feature? I've just been migrating an info site of our university
[mail system](http://poczta.uw.edu.pl/) to Ikiwiki from very static, console handling
Makefile+[WML](http://thewml.org/)+XML+XSL=HTML solution. I have many news files
(`1.mdwn`, `2.mdwn`, etc.) and unfortunately I did very stupid thing. I've commited
all of them in the same revision of our Subversion repo...
Now I have a problem with sorting these files using inline plugin. I can't do
sorting by age, because both old and young news files have the same age. I can't
sort by title too. For example, when I sort them by title, then `9.mdwn` page is
between `90.mdwn` and `89.mdwn` pages... It sucks, of course. Sorting by mtime
also is not a solution for me, because it means that I can't touch/fix old news
anymore.
Do you have any idea how to workaround that issue? --[[Paweł|ptecza]]

Below is my simple patch. Feel free to use it or comment!
I have also 2 considerations for inline sorting:
1. Maybe changing name of `sort` parameter to `sortby` or `sortkey` will
be good idea?
> No, that would break existing wikis. --[[Joey]]
>> It's no problem. You just have `ikiwiki-transition` utility :D --[[Paweł|ptecza]]
1. Maybe you should use `title` sort key for title from meta plugin and `name`,
`filename`, `page` or `pagename` for page names? In the future you can also
sort by meta author, license or another key.

Joey, have you forgotten about that request? ;) --[[Paweł|ptecza]]
> Okie. Here is a different [[patch]] based on my comment above. It doesn't introduce
> a new key, but rather changes the title sorting order. Two caveats:
* I've only tested this in `inline`, not the other places I changed the sort order.
* I'm unsure if the regexp used in the split should be `/(-?\d+)/` instead of `/(\d+)/`.
As written, '-' is interpreted as a hyphen rather than a minus sign.
