cds tab completion with multiple shortcuts and "cds -" about myaliases HOT 2 CLOSED

Plans

• use $COMP_WORDS to check whether the first argument to cds is -
• use $COMP_WORDS to get a sub-array of all of the shortcut names to be deleted
• remove any shortcut names that have already been typed from the completions
• account for tab completions at any spot in the line (ex: cds - <letter(s)>[tab] <shortcut2>)

Turns out that removing shortcut names that have already been typed from the completions is harder than I thought, especially because bash doesn't have an elegant way of checking whether an element exists in an array.
My final attempt was on commit a4d27f6 but then I gave up and put everything back to normal in commit cc444c2.
I might come back to this later, but it seems like code for _cds will be significantly more simple if this feature isn't implemented.
