* will only complain about an inexisting file.
*
* This function is typically called to check that a "file or rev"
* argument is unambiguous. In this case, the caller will want
* diagnose_misspelt_rev == 1 when verifying the first non-rev
* argument (which could have been a revision), and
* diagnose_misspelt_rev == 0 for the next ones (because we already
* saw a filename, there's not ambiguity anymore).
