LFS files and symlinks don't work well

[jaked]

• For large files stored in LFS props.content is a pointer to the actual blob and not the content. It would be nice if there is a flag indicating such cases (or other tooling to deal with such files).
• For symbolic links to files props.content is the content of the target. Symbolic links to directories seems to break the interface - it gets stuck with the loading message and there is an error in the console
