So the line is identical (sans s/^-/+/). Interesting.

I can't seem to reproduce this with some very simple testing. Are you
able to share your files? Or even better, derive a minimal reproduction
recipe?
What happens if you do not do a "remove this line, then add it again",
but instead turn that unchanged line into context? That is, you edit the
hunk into something like this (but without white-space damage):
...
- " call dein#add('flazz/vim-colorschemes')
+ call dein#add('flazz/vim-colorschemes')
call dein#add('Haron-Prime/evening_vim')
...
Adding Phillip to cc, since he was recently working in this area and
might have an idea.
