* Table of long-form options and their behavior. The second column in this
* table must be unique (that is, each long-form option should only be listed
* once), but the other columns are not unique.
*
* The rows in this table can be in any order, but we look them up linearly
* so arguably the most common options should be toward the front.
*
* Note: Not all long-form options have corresponding single-character forms.
* In general, the ones that do are the ones for the single-letter flags
* that existed prior to the introduction of long-form options in 2014.1
