[PATCH 1/2] branch: refactor edit_description command switch case

["Rubén Justo via GitGitGadget" <gitgitgadget@gmail.com>]

From: =?UTF-8?q?Rub=C3=A9n=20Justo?= <rjusto@gmail.com>

Minor refactoring to reduce the return exits in the switch case
handling the edit_description command, so the calls to strbuf_release
can also be reduced.
