What did you do?
./v -g -o vdbg cmd/v && ./vdbg a.v && a

assert true, 'abc
     xyz'

println('hello')

What did you see?

hello

What did you expect to see?

The file is fine, but v vet a.v thinks it is not formatted, even though v fmt -w a.v does not change it

Note: the spaces are present, but are part of the string, started in the assert statement, they are not part of the surrounding V source code, that v fmt changes.
