[PATCH 34/47] completion: zsh: fix direct quoting

[Felipe Contreras <felipe.contreras@gmail.com>]

Apparently using "compadd -Q" is almost always wrong, we want zsh to add
quoting when necessary. However, if we remove the -Q option, that would
make zsh add an extra "\ " at the end of some completions.

We can manually remove the spaces from the completions that have them,
and then add the suffix with the -S option, thus there's no more need
for the -Q option.

This makes completions like "stash@{0}" complete correctly:

  git stash show <tab>
