Emacs opening to files when asked to open one

[Alberto Simões]

Hello

Under MacOS (NS) I added an alias to open files directly on the shell:

[ambs@rachmaninoff VisitasDI]$ alias emacs
alias emacs='/Applications/Emacs.app/Contents/MacOS/Emacs'

This way I can use:
   $emacs foo &

and it works.

But, if I do
  $ emacs public_html/index.html &
(in fact, any file that is not in current dir)
emacs will open it, but also an empt index.html, not sure where.

Any hint on how to solve?
Would this be a bug (weird , but possible), or is there any better way
to alias an emacs command?

Thank you
Alberto
