Find changesets by keywords (author, files, the commit message), revision number or hash, or revset expression.
Use "x == fix (x)" to detect integers rather than floor or round (bug #55347). * find.cc, oct-stream.cc, ov-usr-fcn.cc, idx-vector.cc, oct-inttypes.cc: Use "x == fix (x)" to detect integers rather than floor or round for performance.
