Close #4740

Put `local var` declaration in its own line in lib/git.zsh

In places, the local statement will override the exit code and the written
command won't have the effect intended when it was written.

For example, when it's not inside a git repo the exit code won't be true,
but the local statement will make it true regardless. See #4708.

else.

Some environments (in my case, cygwin) have PATH variables with directories
with spaces in them, breaking colored-man.
Adding quotes around the PATH environment variable makes the plugin run OK.

Close #4103

When the user is asked to update oh-my-zsh it says "[Oh My Zsh] Would
you like to check for updates? [Y/n]:". When the user agreed to update
the next text would say "Upgrading Oh My Zsh" which is inconsistent
with the question.
