Link to _file rather than _raw if there's split pages

E.g.:

= path/to/myfile.txt
{file}

whould generate a breadcrumb like:

(root)/path/to/<myfile.txt>{file}{split}

where {split} is a possibly new argument that ensures it links to split if there are split pages, and not the current:

(root)/path/to/\a[myfile.txt]

This would make file autogen much more useful and visible. The general premise is that we should link to split {file} preferentially always.
