2.19.0

Fixes

• Reverted a breaking change introduced in 2.18.0 that caused the threading macro --> to be indented differently from -> and ->> (#375).
• Added and fixed Edebug specifications for many Dash macros (Philipp Stephani, #380, #381).

New features

• The combinators -on, -flip, -not, -andfn, and -orfn now return variadic functions that take any number of arguments (#308).
• New combinator -rotate-args similar to -flip, but for arbitrary arglist rotations (suggested by @vapniks, #72).
• New function -every and its anaphoric macro counterpart --every. They are like the existing -every-p and --every-p, respectively, but return the last non-nil result instead of just t.
• New macro --partition-after-pred which affords -partition-after-pred better performance (Per Weijnitz, #362).
