fonts are very fat in my gvim --- help wanted
Ubuntu 16.04

VIM - Vi IMproved 8.0 (2016 Sep 12, compiled Mar  5 2018 09:31:07)

SpaceVim 0.7.0-dev

~/.local/share/fonts/
```
DejaVu Sans Mono Bold for Powerline.ttf             mtextra.ttf
DejaVu Sans Mono Bold Oblique for Powerline.ttf     symbol.ttf
DejaVu Sans Mono for Powerline.ttf                  Ubuntu Mono derivative Powerline Nerd Font Complete.ttf
DejaVu Sans Mono Oblique for Powerline.ttf          WEBDINGS.TTF
devicons.ttf                                        wingding.ttf
DroidSansMonoForPowerlinePlusNerdFileTypesMono.otf  WINGDNG2.ttf
fonts.dir                                           WINGDNG3.ttf
fonts.scale
```

I hope to set `guifont` to `DejaVu\ Sans\ Mono\ 12` if it is possible.

Thanks!
