powerline

Changes:

  modules (e.g. powerline.segments.common.vcs).
• Added support for different tag formats provided by tagbar plugin.
• Improved non-unicode locales handling.
• Improved non-unicode filenames handling.
• Improved Vim troubleshooting: it now runs powerline-lint automatically.

  never allowed to change it.

  remembered once and never changed.
