I guess mailinglists are not my thing huh?

Yeah, I think it would go in the 'c' of 'MoSCoW', but it could be very
useful when done right.

I reckon more input from actual maintainers would be needed then.
Junio: aside from the original list with suggestions you provided,
could you shine your light as git maintainer on this?

It sounds like it would not be too hard to implement' maybe another
'C' in 'MoSCoW' (or perhaps that first 'C' should be a 'W'...)

I'm not familiar with pickaxe, what you suggest sounds like grepping
the content also throughout history?

I understand what you want, a search for specific content, from old to
new, stopping when you have a match?

I used the former, never tried the latter :).

I'm not sure what gain that would bring though, as it can only provide
end dates, not 'starting work now' timestamps...
