annotate libinterp/operators/op-dm-dm.cc @ 17402:b6867a09d7cf

Find changesets by keywords (author, files, the commit message), revision number or hash, or revset expression.
Return correct status code for copyfile, movefile. * scripts/miscellaneous/copyfile.m, scripts/miscellaneous/movefile.m: Return correct status (inversion of system function). Put input validation first. Use single quotes to simplify expressions. Redo docstrings.
