That is strange. I don't see that behavior using vim 7.2.148. When
I use your mappings and I hit Enter on a quickfix line referring to
an already-open buffer, vim opens a new window containing that
buffer. I get a new window each time I press Enter in the quickfix
window, but no "[No Name]" buffers.

The quickfix window is maximized for me.
What is the <Esc> for? I didn't understand its purpose so I removed
it from both macros and the behavior seemed to be the same.

Again, it all works for me. What version of vim are you using?
Try starting vim with "-u NONE" to avoid interfering settings.
Since your goal is to open a new window only if a window containing
the desired buffer doesn't already exist, take a look at
:help switchbuf
I've never been able to use it to achieve the results I've wanted,
but it may do what you want.
