git remote报错解决办法

现象：

cuiwe@cuiwenqi MINGW64 /e/lattice_prj/lattice_sim (master)

$ git remote add origin git@gitee.com:cuiwenqicn/lattice_mipi_csi_sim_demo.git

usage: git remote add \[\]

-f, --[no-]fetch      fetch the remote branches
--[no-]tags           import all tags and associated objects when fetching
                      or do not fetch any tag at all (--no-tags)
-t, --[no-]track <branch>
                      branch(es) to track
-m, --[no-]master <branch>
                      master branch
--[no-]mirror[=(push|fetch)]
                      set up remote as a mirror to push to or fetch from

原因 ： origin后面的空格有问题，发生错误是因为在命令的origin后面有一个不可见的（或容易错过的）非中断空格（U+00A0）或其他一些空白字符。
