Bat autocomplete with zsh is buggy

[alichtman]

Whenever I enter $ bat <TAB> to prompt zsh autocompletion, it autocompletes cache instead of cycling through available files in the directory, like zsh does for other programs.

Typing $ bat <First Letters> results in zsh saying no completions can be found.

I've confirmed that cat does not exhibit this behavior, and none of the other tools I've installed with brew do this either.

Here's the result of $ cat <TAB> <TAB> <TAB>.

Here's $ bat <TAB> <TAB> <TAB>

The issue here is that bat prefers tabbing into the options over tabbing into the files it can print out.

I upgraded to zsh 5.7.2 from 5.7.1 and can't replicate the $ bat <TAB> <TAB> <TAB> example from above. So maybe it's a zsh issue and not a bat issue?

I've just run into another issue which stops me from bat-ting multiple files at a time with autocomplete.

$ bat <Tab to autocomplete first file> <Tab>

The second tab always fills in cache for me.

Another issue I discovered is that when you autocomplete cache, the next thing autocompleted is cache, a second time. Only after that second cache will zsh give me the option to scroll through options.

Upon selection, the command is invalid.

This looks like a duplicate of #372 and should be "fixed" in the next release (by not providing a shell completion file).
