Error when commit message contains more than one word (space separated) on Windows 10

[no-realm]

Describe the bug
Commit messages with more than one word fail with the error below.

+ cmd /c git commit  -m \"test1 test2\"

error: pathspec 'test2\"' did not match any file(s) known to git

Press enter to return to lazygit

And commit messages with one word have incorrect commit messages (when viewed later):

\"test1 test2\"

To Reproduce
Steps to reproduce the behavior:

1. Download or compile lazygit
2. Open repo with lazygit (in either cmd or powershell)
3. Change a file and stage the change
4. Commit with a commit message that has more than one word (space separated)

Expected behavior
Support commit messages with more than one word.
Correctly formatted commit messages.

Desktop (please complete the following information):

• OS: Windows 10 64-bit
• Lazygit Version v0.13 (prebuilt from releases) and commit below
• c173ebf

Additional context
Looks very similar to a previously closed issue #141.
