For short single commands, prefer a one-liner `for` with the zsh syntax:
```
for x (foo bar) print ${x}
```
Otherwise just place `; do` on the same line as the POSIX `for ... in`:
```
for x in foo bar; do
print ${x}
done
```
Closes#268
that use the git-branch-delete-interactive function.
Thanks to @Mikachu for helping with the completion function
implementation over the #zsh chat.
Closes#265
that prompts if upstream remote branch(es) should be deleted too. As
with `git branch`, the function supports multiple branches as params,
and also the `-r`/`--remotes` param. Update `gbx` and `gbX` to use this
function.
Also update `git-stash-clear-interactive` to have multiple tests instead
of multiple nested `if`/`then`/`fi`. (Simpler syntax, IMHO)
