prettier-plugin-sh fails to format standard VisualStudio.gitignore file

[interfrastic]

I configured prettier-plugin-sh to format my .gitignore files and this worked fine until I tried to format the standard .gitignore provided for Visual Studio Code:

https://github.com/github/gitignore/blob/main/VisualStudio.gitignore

Attempts to format the file fail with this error:

$ curl -OfsSL https://github.com/github/gitignore/raw/main/VisualStudio.gitignore
$ md5sum VisualStudio.gitignore.txt

$ head VisualStudio.gitignore.txt

# User-specific files

$ npx prettier --write VisualStudio.gitignore
VisualStudio.gitignore

The workaround is to comment out these two lines:

$ diff VisualStudio.gitignore.orig VisualStudio.gitignore
275,276c275,276
< *- [Bb]ackup ([0-9]).rdl
< *- [Bb]ackup ([0-9][0-9]).rdl

$ npx prettier --write VisualStudio.gitignore
VisualStudio.gitignore 31ms (unchanged)

Just like #278

I'm sorry, but actually ignore files are not officially supported by https://github.com/mvdan/sh what means only basic and simple ignore files usage cases can be handled correctly. We can not do much inside.
