Subject: 30.0.50; eshell: grep -H and -n flags are hardcoded and the latter
 cannot be overwritten
Date: Mon, 22 Apr 2024 02:30:22 +0100

Hi,

I've noticed that -Hn flags are hardcoded when calling eshell's grep
command. Specially in pipes, where -H prints a noisy (standard input)
prefix for every line, those flags are rarely what I personally want,
and I'd like to have the option to disable them. For -H i can add -h to
the call, or even redefine eshell/grep to not use -H, but there's no
flag to disable -n.

Thanks!
