  Fix bugs for status with spaces and reloaded attrs This fixes two bugs: * Issue #728 where git_status_file was not working for files that contain spaces. This was caused by reusing the "fnmatch" parsing code from ignore and attribute files to interpret the "pathspec" that constrained the files to apply the status to. In that code, unescaped whitespace was considered terminal to the pattern, so a file with internal whitespace was excluded from the matched files. The fix was to add a mode to that code that allows spaces and tabs inside patterns. This mode only comes into play when parsing in-memory strings. * The other issue was undetected, but it was in the recently added code to reload gitattributes / gitignores when they were changed on disk. That code was not clearing out the old values from the cached file content before reparsing which meant that newly added patterns would be read in, but deleted patterns would not be removed. The fix was to clear the vector of patterns in a cached file before reparsing the file.
