Secure umask enforced during installation.

Browse source 
For safety, a umask of 022 prohibiting both group and other writability is now
enforced during OMZ installation. In theory, this should reduce the likelihood
of subsequent compinit() failures due to insecure directory permissions under
all platforms except for default Cygwin installations (in which Windows ACLs
override POSIX umasks).

# Prevent the cloned repository from having insecure permissions. Failing to do
# so causes compinit() calls to fail with "command not found: compdef" errors
# for users with insecure umasks (e.g., "002", allowing group writability). Note
# that this will be ignored under Cygwin by default, as Windows ACLs take
# precedence over umasks except for filesystems mounted with option "noacl".
