I chose -F back then because it does not print the definition of the
completion function, so there is less stuff to throw away immediately.
However, the run-time difference seems to be barely measureable (i.e.
'time declare -f _git_config >/dev/null' vs. 'declare -F _git_config
 >/dev/null' sometimes shows 0.001s difference), so I'm fine with this
change.

-z?  I think you wanted to use -n here, like at the other places.

Nit: why "if [[ ... ]]"?  FWIW "if [ ... ]" would be enough.
