Diff fails if your home directory has a space (tested on windows)

[angelidis]

hi Bai,

thank you for developing this amazing plugin. i think i found the following bug.

1. assume home directory: "C:\Users\FirstName LastName"

2. launch undotree

3. the Diff window will say: [31;1mCompare-Object: [31;1mA positional parameter cannot be found that accepts argument 'C:\Users\FirstName'.[0m

environment: neovim-9.5 windows 11
