[PATCH] gnu: wxwidgets: enable extended regular expressions.

[Danny Milosavljevic]

Hi,

this patch enables extended regular expression support in wxwidgets. It's 
needed for kicad. 

I tried to test the other packages that depend on wxwidgets (wxmaxima and 
audacity) but even without the patch they are in various states of brokenness. 
See my bug reports on the problems. These are: audacity: local help files 
share/audacity/help/ not installed and crash in wxmaxima on Save As.

So it's not tested in wxmaxima and little tested in audacity. I think the risks 
are low anyway and it's likely that it will work. KiCAD works fine with it.

* gnu/packages/wxwidgets.scm (wxwidgets): enable extended regular expressions.
