Autocompletion

When the following lines are added to ~/.bashrc or run in the current session, then tldr will autocomplete, which means possible tldr page names will be suggested when tapping the Tab key twice on an incomplete tldr page name:

cachedir=~/.local/share/tldr/pages # Or whatever else the location of the tldr cache is
complete -W "$(q=($cachedir/*/*); sed 's@\.md @ @g' <<<${q[@]##*/})" tldr
