[PATCH] Change in increment_mtime for BSD compatibility of test suite

[Felix Geller <fgeller@gmail.com>]

Use `-t' option rather than `-d' which is not supported by BSD's
touch. I'm not sure whether this is the cleanest way to do this, please
let me know if there is a better way. There are additional changes
(e.g., sed does not support `-r' but instead `-E') but they seem to be
incompatible between GNU and BSD. What's the recommended way to handle
this?

Cheers,
Felix
