Fixed an issue in which the file path containing spaces could not be grepped

[ZeroOnePro]

When running a script on path "/home/foo bar/test.md", there was a problem that the file path was not grep properly like this

grep ./home/foo/: No such file or directory grep bar: No such file or directory grep name: No such file or directory grep test.md No such file or directory

So I solved the problem by adding a comma to $gh_src

There was a problem when using it with the insert flag, but the test did not reflect it, so I modified it
