argv-array: add pop function
Sometimes we build a set of similar command lines, differing
only in the final arguments (e.g., "fetch --multiple"). To
use argv_array for this, you have to either push the same
set of elements repeatedly, or break the abstraction by
manually manipulating the array's internal members.
Instead, let's provide a sanctioned "pop" function to remove
elements from the end.
