Set up config files as soon as possible such that 'got fetch' has enough information in order to resume an interrupted clone operation. We need to receive at least a default HEAD branch name from the server before we can set up our configuration files. The previous code also verified whether the default branch name supplied by the server resolved to a commit received in the pack file. This check cannot be done early but a wrong branch name in a config file can be fixed easily.

The generated Git config file instructed Git to fetch all branches rather than the default branch as was intended. Check generated configuration files in all clone tests in order to catch such problems in the future.

Storing a resolved ID for each reference list item was a bad idea. This ID cannot be resolved if a symbolic references points to a reference which does not exist. Such symrefs were skipped by got ref -l as a result. Just let users of reference lists resolve the IDs as needed.

This makes it easy to deal with files that were deleted from disk by external tooling which modified the work tree. Such files are left in missing (!) status and can now be marked for deletion in bulk via 'got rm -s\! -R .' For consistency, modified (M) files can now be removed with 'got rm -s M' which implies 'got rm -f'. Prompted by feedback from krw@

Advantages over using grep are that the list of codes is validated against a list of known status codes, and that it is easier to match staged files which can display status codes in one or both of two columns. Prompted by feedback from krw@

With -R, the -P option did not show any paths. Regression test added here demonstrates the problem.

Remove the alias 'got in' for 'got init'. The 'in' alias was too close to either 'init' or 'info'. ok tracey, millert
