Duplicate variables in doc/tlib.txt

[heavenshell]

Hi,

I've got error messages when I startup Vim.
I use pathogen.

Error messages are below.

Error detected while processing function pathogen#helptags:
line    4:
E154: Duplicate tag "g:tlib#vcs#def" in file /Users/heavenshell/.vim/bundle/tlib_vim/doc/tlib.txt
E154: Duplicate tag "g:tlib#vcs#executables" in file /Users/heavenshell/.vim/bundle/tlib_vim/doc/tlib.txt

I think https://github.com/tomtom/tlib_vim/blob/master/doc/tlib.txt#L772 and https://github.com/tomtom/tlib_vim/blob/master/doc/tlib.txt#L781 were duplicated.

Thank you.
