Refactor to remove two loops over the entire list of candidates.
Format descriptions only for completions that are actually going to be
displayed, instead of for all candidates.
Format descriptions inline in completions array, removing need for a
command substitution/subshell and a printf escape per displayed
completion.
Using a command substitution, i.e. a subshell, with `printf` is
expensive for this purpose. For example `__*_format_comp_descriptions`
is run once for each completion candidate; the expense adds up and
shows when there are a lot of them.
* Bash completion v2
This v2 version of bash completion is based on Go completions.
It also supports descriptions like the other shells.
