Emacs doesn't handle long line lengths very well. If you accidentally rg a file
a file that has very long line lengths it can freeze emacs. This prevents rg
from returning any results with more than 150 characters. Instead, it will
indicate that there were results in that file but they were elided.
rg tries to be smart about printing line numbers in its output (if running
inside a TTY or not). On Windows, sometimes (always?) it chooses not to print
line number. However, we always want line numbers, so we need to pass -n flag.
Also fix a minor grammar mistake.
