[tex-k] [feature] Can kpathsea have a shell completion?

[Wu Zhenyu]

Excuse me:

Can kpathsea have a shell completion? That is,
if users `kpsewhich --print-completion XXsh` in their bashrc/zshrc, they can:

```
$ kpsewhich -<TAB>
option
-cnf-line          parse STRING as a configuration file line.
-expand-braces     output variable and brace expansion of STRING.
-expand-path       output complete path expansion of STRING.
-expand-var        output variable expansion of STRING.
-help-formats      display information about all supported file formats.
-must-exist        search the disk as well as ls-R if necessary.
...
```

Thanks!
