I'm curious why (4) doesn't work for you. I assumed you came to the
problem by one of:
- you wanted to know which options "git show" had, so you looked in
the manpage. Nothing told you about "--color-words", nor referred
you to a list of diff options. With (4), you would find that it
accepted all diff options, and then go read the list of diff options
(if you weren't already familiar with it).
- you knew about --color-words, and wondered if "git show" supported
it. In the current case, searching the page turns up nothing. In
option (4), a search would find it (with a reference to diff options
if you wanted more details).
The downside is that you sometimes have to be referred. The upside to me
is that it becomes explicit that there is a concept of "diff options"
that you can look up easily and which we can refer to easily in other
parts of the manual. That helps establish a mental model of how git's
options work.
So is it just that being referred is annoying, or something else?
