de-quirkify execute-extended-command
On RET, execute the command on the selected line rather than what the user typed. This saves a TAB (to expand the entry) and is more in line with the other completion commands.
replace TAILQ_EMPTY/INSERT_HEAD/TAIL dance with a single TAILQ_INSERT_TAIL
Now that all the queues are correctly initialised, there's no need for that dance.
fix redirect & history
the reload command doesn't push the current url to the history anymore.
reorder minibuffer stuff
and while there also rename the bogus completing_read to minibuffer_read. To get a ``completing-read'' one has to call enter_minibuffer with the right parameters.
