A collection of minor error handling fixes: - use an error message in lower case, following the usual style - quote filenames in error messages to make them easier to read and to decrease translation load by matching other 'stat' error messages - check for and report errors from 'read', too - avoid being confused by a gc.log larger than INT_MAX bytes
