Regarding (info "(grep) Context Line Control") To get exactly this great output $ seq 33|grep --context=4 --label= --with-filename 5$ without further tips on the page, the user won't figure it out. Even worse, if the input is from a file, not stdin, even I can't figure it out.
Unfortunately I don't understand this bug report. I don't know what the "it" is that people would want to figure out.
'grep' has a lot of options to control output format (maybe too many options), they interact in odd ways, and it would be impractical to describe all their interactions. If there's a particular use case that should be in the manual then we could do that, but I don't know what that use case would be here.
A specific proposed patch to the manual would make the case more clear.
