@asutosh936 I agree with @anmolnar That directory exists, it is currently
in version control, and I don't think any generated files actually end up
there. My guess is that it is there purely for historical reasons and to
contain the rcc.jj file.
In other words, I don't think your change to the gitignore will impact that
directory. According to the gitignore documentation
(https://git-scm.com/docs/gitignore):
> If the pattern does not contain a slash /, Git treats it as a shell glob
pattern and checks for a match against the pathname relative to the location of
the .gitignore file (relative to the toplevel of the work tree if not from a
.gitignore file).
Since there are not any top level files called `generated` I don't think
this line in the gitignore has any impact on the repository. Am I missing
something here?
