bug#36027: [PATCH] Use lexical-binding in morse.el and studly.el and add tests

[Stefan Kangas <stefan@marxist.se>]

[-- Attachment #1: Type: text/plain, Size: 187 bytes --]

I've added the lexical-binding header to morse.el and studly.el and
included tests for these files.  Another small step towards a core
with full lexical-binding...

Thanks,
Stefan Kangas
