bash completion not working: uses deprecated have()

[Paulo Marcel Coelho Aragão]

bash completion, defined in /usr/share/bash-completion/completions/unar, doesn't work: the completion is not dynamically loaded, because it uses deprecated helper function have().

According to /usr/share/bash-completions/bash_completion, which defines the helper functions:

# Backwards compatibility for compat completions that use have().
# @deprecated should no longer be used; generally not needed with dynamically
# loaded completions, and _have is suitable for runtime use.

and at the end of the file:

unset -f have
unset have

which means: function have() is not available for usage. The bash completion for unar and lsar conditionally defines _unar and the comspec for unar and lsar:

have unar &&
_unar()
{
...
} &&
complete -F _unar unar

have lsar &&
_lsar()
{
...
} &&
complete -F _lsar lsar

All instances of have should be replaced by _have.
