do not update symlinks which are already up-to-date
This fixes spurious 'U' notifications for symlinks during 'got update' that occurred even when the work tree was fully up-to-date. Observed on a work tree of the FreeBSD src repo and reproduced in our test suite by adding a no-op update at the end of a test which deals with updating symlinks.
fix bug where 'got up -c commit path' deleted unrelated files from work tree
Problem reported by Timo Myyrä
add a -q option to tests for quiet output and use it for 'make regress'
Previous default output remains when test cases are run individually. ok tracey
