Fix git log display errors without truncation

Git log subject truncation is okay, but at this point still does unnecessary
padding to the specified number of characters. We fix the display errors instead
by modifying the `less` pager options. Apparently `R` ensures more correct
displays than `r`, while still allowing control characters like those for
colourisation to work.
