make --preview accept grep lines
add tests

grug [OPTIONS]

  -A, --above <LINES_ABOVE>        Include LINES_ABOVE lines above each line from stdin in the hunk
  -B, --below <LINES_BELOW>        Include LINES_BELOW lines below each line from stdin in the hunk
  -C, --context <CONTEXT_LINES>    Include CONTEXT_LINES above and below each line from stdin in the hunk
  -e, --expand                     Expand the lines from stdin into hunks
  -h, --help                       Print help information
  -p, --preview                    Preview diffs from the hunks passed to stdin
  -w, --write                      Replace lines in files based on input from stdin

Examples

To expand lines from stdin into hunks:

echo "src/main.rs:10" | grug --expand

To preview diffs from the hunks passed to stdin:

echo "src/main.rs:10" | grug --preview
