+decimal and hex literals.  It works like C-a/C-x in Vim, i.e. searches for
+number up to EOL and then increments or decrements and keeps zero padding up
+(unlike in Vim).  When a region is active, as in Evil's visual mode, all the
+numbers within that region will be incremented/decremented (unlike in Vim).
+
+It is a fork of https://github.com/cofi/evil-numbers, which is unmaintained.")
