Autocompletion does not work with relative paths anymore

[cactushydrocodone]

Describe the bug

Autocompletion does not do relative paths.

To reproduce

1. Go into your home directory (/home/mark)
2. Type in chezmoi edit .config
3. Chezmoi will not autocomplete

Expected behavior

Chezmoi should be able to autocomplete relative paths

Output of command with the --verbose flag

There is no output as the autocomplete does not generate one.

Additional context

If you do chezmoi editand hit tab twice, it shows the absolute path of the home directory (like /home/mark) and after that, autocompletion works.

If you enter the relative path manually after chezmoi edit like chezmoi edit .config/i3/config it opens the file without issue.

I downgraded the chezmoi package and the issue does not appear until chezmoi 2.9.3-1

Thanks for reporting this. This is a definite bug in chezmoi, most likely introduced by #1736.

Completion still fails when using paths that start with ~ or a variable (e.g. ~/.config/foo or $XDG_CONFIG_HOME/foo), which both worked when using default fish completion. Also, it would be extremely helpful if completion added trailing / to enable the use of successive tab completions for files in subdirectories.

Edit: Version 2.9.5 and using chezmoi completion fish > ~/.config/fish/completion/chezmoi.fish.

This is due to a bug in cobra's fish completions. I've opened spf13/cobra#1577 to report it.

The latter part about the trailing slash also affects bash.
