Allow hidden directories to be found

[evanthegrayt]

We need a configuration variable to and runtime options to find repositories that start with a dot. NOTE that cdc .whatever will always work, it's just that they currently don't show up in tab-completion.

Line 570

for fulldir in "$dir"/*/; do

Should become something like

if $ALLOW_DOTFILES; then
  dirlist = {,.}$dir/*/
else
  dirlist = "$dir"/*/
fi

for fulldir in "$dirlist"; do
