Steps to reproduce:
1. open https://src.fedoraproject.org/rpms/texlive/tree/master
2. open "texlive.spec"
3. wait for the file to load

What happens:
Pagure itself loads fine, but the specfile cannot be loaded. The connection times out instead.

What should happen:
Display file or display a message that the file is too big to load.

Additional info:
I cloned the git repository and the file has a size of 8.7MiB.

Tested on Firefox 57 and Epiphany.
