add: Consistently treat files in a dotdir as dotfiles, even when ran inside that dotdir

Assistant and smudge also updated.

This does add a small amount of extra work, getting the TopFilePath.
Not enough to be concerned by.

Also improve documentation to make clear that files inside dotdirs are
treated as dotfiles.

+
+Because creating a .gitignore followed by `git-annex add` would then blow the
+user's foot off. And this would be a very common foot-shooting opportunity,
+and .gitignore is only the perhaps most common trigger for it.
+
+Files in dot directories are generally less common, outside of course of
+.git and $HOME. Which is the only reason I'm willing to consider changing
+the dotfiles handling to not include those.
+
+But, .config/ seems to me to perfectly match what dotfiles *are*, which is
+files that are configuration that are named with a name starting with a
+dot in order to keep them from cluttering up `ls`. Just because in your use
+case you don't want to check those into git as dotfiles does not seem like
+a good argument for git-annex to not treat them as dotfiles by default.
