Formatter: Use pathshorten() instead of substitute()

Browse Source 
The default formatter uses a hand-build regexp for shortening the path
in the tabline. However, since it uses the \w  regex atom, this won't
match e.g. cyrillic letters.

To fix this, use the builtin pathshorten() function which does handle
this case correctly. For a test, use e.g. 'D/Учёба/t.c'
