Simple: Your vimrc is run only once, at startup. At that point,
buffers have already been created (but not yet loaded) for all files
mentioned on the vim (or vimdiff or gvimdiff or...) command-line.
"b:mckgitstatus", a buffer-local variable, is only seen from the
buffer which was current while sourcing the vimrc, probably the first
one.
If you want your :if .. :else .. :endif construct to apply to all
buffers mentioned on the command-line, it should be wrapped in a
function called from an :argdo statement. OTOH, if you want your
autocommands to apply to all non-diff buffers whenever created, your
MyGitStatus and MyGitPost functions should test &l:diff directly
rather than b:mckgitstatus. CAUTION:
