Patch parse error: Explicitly state src-prefix & dest-prefix for git diff command

[tye-singwa]

Hi!
i've encounter an issue when using this tool. It failed with patch parsing error.
From logs i could see that somehow my system setup uses different prefixes while producing patch file.

Here is first line of produced patch:

diff --git i/node_modules/@storybook/ui/paths.js c/node_modules/@storybook/ui/paths.js

I suggest adding options (https://git-scm.com/docs/git-diff#Documentation/git-diff.txt---src-prefixltprefixgt & https://git-scm.com/docs/git-diff#Documentation/git-diff.txt---dst-prefixltprefixgt) explicitly here

patch-package/src/makePatch.ts

Lines 211 to 217 in 5c2c92b

	const diffResult = git(
	"diff",
	"--cached",
	"--no-color",
	"--ignore-space-at-eol",
	"--no-ext-diff",
	)

like this

 const diffResult = git( 
   "diff", 
   "--cached", 
   "--no-color", 
   "--ignore-space-at-eol", 
   "--no-ext-diff", 
   "--src-prefix=a/",
   "--dst-prefix=b/"
 );

Thanks
