I agree.

Stepping a notch back, wasn't the original request to have a command
that would display a specific commit?  If so, that's not a "log"
command, that's closer to a "diff" command.  And don't we already have
a "diff" command which shows diffs for a specific revision?  If not,
let's provide that.  The fact that Git can show diffs in some
sub-commands of 'log' shouldn't dupe us into thinking that this is
about "log" in any way.

A command that searches the log entries for a string/pattern should be
a separate command, which could be a "log" command.

Thanks.
