attribute abbreviations

Defines the current abbreviations as an array. This is only used if extra_space is turned on.

If one is abbreviating “President” as “Pres.” (abbreviations = [“Pres”]), then the results of formatting will be as illustrated in the table below:

extra_space  |  include?        |  !include?
  true       |  Pres. Lincoln   |  Pres.  Lincoln
  false      |  Pres. Lincoln   |  Pres. Lincoln
