runtime(doc): Recover some missed commas and periods in starting.txt Commit: https://github.com/vim/vim/commit/78c189837ae6a03fa5fbb62eabde66e3da9253a3 Author: Aliaksei Budavei <0x000c70@gmail.com> Date: Mon Mar 18 19:24:52 2024 +0100 runtime(doc): Recover some missed commas and periods in starting.txt Also: - Insert some missing words; - Strive for consistency with capitalisation of words; - Improve shell alias examples. The gvim words were left alone for now, but they deserve to be treated like proper names, GVim or GUI Vim, unless these refer to executable filenames (on *nix systems). closes: #14194 Signed-off-by: Aliaksei Budavei <0x000c70@gmail.com> Signed-off-by: Christian Brabandt <cb@256bit.org>
