[PATCH 1/5] git-completion.bash: separate some commands onto their own line

[Denton Liu <liu.denton@gmail.com>]

In e94fb44042 (git-completion.bash: pass $__git_subcommand_idx from
__git_main(), 2021-03-24), a line was introduced which contained
multiple statements. This is difficult to read so break it into multiple
lines.

While we're at it, follow this convention for the rest of the
__git_main() and break up lines that contain multiple statements.
