po/es: Fixup whitespace

There are quite a few places where a line ends `foo"`, and the next line
picks up `"bar`; with neither line containing a space separating "foo" from
"bar".  The results in the words getting munged together in to "foobar"
rather than "foo bar".

Here's how I searched for these:

    cat *.po|ruby -e 'puts STDIN.read().gsub(/"\n\s*"/, "\"\"")'|sed -r 's/^msg(str|id) """/msg\1 "/'|grep -vE '^msgstr\s+"Project-Id-Version:'|grep '\S""\S'

There are 5 false-positives that are reflections of where msguniq decided
to split a flag or path in the .pot file.
