Thanks to the input file's dual nature, so to speak, using xxd(1)
to filter and edit binary files makes restoring the cursor position
broken. Fix that by ignoring the appropriate file type in the code
that restores the cursor position.
While there, refactor the code a bit to save a few CPU cycles and
to keep the line lengths in check, and use longer versions of some
of the commands, to make it slightly more consistent and more
understandable to newcomers.

Another autocommand. This time it is used after reading any file. The
complicated stuff after it checks if the '" mark is defined, and jumps to it
