[PATCH] dim: replace egrep with grep -E

[Lucas De Marchi]

Fix shellcheck:

In dim line 1489:
echo "$diff_result" | egrep '^[+-]' | egrep -v '^[+-]{3}'
                      ^-- SC2196: egrep is non-standard and deprecated. Use grep -E instead.
                                      ^-- SC2196: egrep is non-standard and deprecated. Use grep -E instead.
