There are many mentions of commands using inline-verbatim or
emphasis ('). We just mention the command themselves, not specific
invocations like `git am <opts>`. Let’s link to them instead.
There are also many such mentions which then link to the command right
afterwards. Simplify to just using a link.
Also remove “see <gitlink>” phrases where they have now already
been mentioned.
