Subject: [PATCH] Small improvements of po extension
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

• Fixed shortening of message. It was not showing more than one digit for fuzzy and untranslated strings.
• Fixed case when starting translation (0 translated), and accomodated for some bigger po catalogs (more than 1000 strings)
• Add support for Windows (I use it on Windows, it works fine with latest Vim. Didn't test Neovim or older Vim versions, though)
• Add one extra space character to the right of the output string
