**Describe the solution you'd like**
I need to maintain the AUR package [nerd-fonts-noto-sans-mono-extended](https://aur.archlinux.org/packages/nerd-fonts-noto-sans-mono-extended).
This package is based on three sources:
* NotoSansMono: that I will take from "https://github.com/notofonts/latin-greek-cyrillic/releases/download/NotoSansMono-v2.014/NotoSansMono-v2.014.zip"
* Your font-patcher: https://github.com/ryanoasis/nerd-fonts/releases/download/v3.2.1/FontPatcher.zip
* src/glyphs content: https://github.com/ryanoasis/nerd-fonts/tree/master/src/glyphs

With the latest version I cannot retrieve the `src/glyphs` subdirectory by `svn` and I'm forced to use `git`. It means that the user that wants to install this package, needs to clone the entire `nerd-fonts` repository that needs time and GBs of space.

A good solution could be create a specific release or branch for src/glyphs to be patched, so they can be retrieved by git without pulling the entire repository.
