Autocompletition fails when calling emacs with a non-existent file

[kantholtz]

When I try to open a file with emacs and that file does not exist a rather long error message gets printed when I try to do autocompletition by pressing TAB:

$ fish -v
fish, version 2.0.0
$ mkdir foo; cd foo; du
0    .
$ emacs x

...or any other character and then I press TAB for autocompletition

If the file exists, no error gets printed. If I use any other program (like "touch" for example) no error occurs. I have only observed this with emacs. I'm using version 24.2.1. As you can see in the error messages I'm on OS X and using the latest fishfish formula from brew.

__fish_filter_mime doesn't do anything good if there's no results. This should fix it. Thanks for reporting this.

I still have this issue on OSX 10.7.5 and emacs 24.3.1.

This error happens when completing absolutely anything :

• When completing an empty argument, a space is added at the end of the command, and the directory content is not printed.
• When completing a valid or an invalid file, the behavior is ok.

Other fact, the behavior described above also happens on Debian wheezy, but __fish_filter_mime does not print all these error messages.

Another case of OS X's seq doing the wrong thing when passed 0
Should be fixed as 79f8d5c
Thanks for reporting this (again)!
