Subject: edit: Add geiser-insert-actual-lambda.
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
Some projects use λ, some use lambda, and it is convenient to be able to use the
same mapping engraved into muscle memory for both. Therefore this commit adds a
new variable that allow geiser-insert-lambda to do both, depending on the value.
* elisp/geiser-edit.el (geiser-insert-actual-lambda): New variable.
(geiser-insert-lambda): Respect it.
