Git has a limit of 4096 characters for a filename, except on windows when git is compiled with msys. It uses an older version of the windows api and there's a limit of 260 characters for a filename.
As mentioned in the Git Bash wiki, the `core.longpaths` config option tells git to use the UNC file paths (i.e. prepend `\\?\`). This works as long as the base path isn't too long.

Please, add an option to run `git clone` with a `-c core.length true` parameter.
