branch: add '--no-name-prefix' option

valeriyoann · valeriyoann · commit af9dbc8822f9 · 2026-03-04T15:00:26.000+01:00
This patch adds the '--no-name-prefix' option to prevent adding any
prefix to the branch being created, whether through the '--name-prefix'
option or the 'branch.namePrefix' configuration parameter.
