grep w/o group separator

[der.hans]

moin moin,

Is there an option for grep to use -(B|A) without the group separator?

"Places a line containing a group separator (--) between contiguous groups
of matches."

$ grep -B 1 -E 'name:|2019:' _data/sponsors.yml | tail

- name: Dragonchain
--
   sponsorships:
     2019: bronze

- name: Ubuntu-PNW
--
   sponsorships:
     2019: thanks
----

I can grep them out with another grep, but I'd rather just not have them.

ciao,

der.hans
