Add Fish example
Add another location used by Bash
Add the filename used by ZSH.
If you want to use of, it needs to be written Path of shell completion files or something similar. I would just keep this as it was.
There should only be one directory here, so that committers do not choose randomly where to put the files.
Looking at the bash_completion code, it looks like etc/bash_completion.d is for legacy scripts, and share/bash-completion/completions is for recent scripts.
It would be preferable to say something specific, or to not say anything.
