Hi,

I've made this little patch (attached file) to add auto-identation to 
the text editor.
With this patch, spaces and tabulations at the beginning of the previous 
line will automatically be added at the beginning of a newline when the 
user press Enter in the text editor.
That makes typing python source in blender much easier.

Thanks in advance,
