test-ssh: test absolute path that exists

subrepo: improve lookup error messages

run-tests: move build/ directory to HGTMP Before, running a test would give you a build/ directory in the root of your Mercurial source tree. The directory had a full copy of the the source, so a grep in '**/*.py' would find files inside build/.

setup: slight simplification

Makefile: remove the build folder manually Given a system Python version of 2.6, the following won't clean up build: $ make local PYTHON=python2.7 $ make clean Distutils only cleans up build subdirectories for the current Python version. This patch cleans up the build folder even if PYTHON=python2.7 isn't specified to clean.

Makefile: remove all .so files during clean This ensures .so files in hgext are cleaned up.

keyword: support rollback by restoring expansion to previous values Prevent spurious differences in the working directory after a rollback. Add tests for several rollback situations.

keyword: do not expand at all during diff Always shrink and never expand keywords during a diff operation. Avoid user distraction e.g. because of spurious differences appearing in the commit editor.

keyword: restore restricted read mode value after overwriting Even though just enforcing expansion after overwriting files in the working directory caused no problems that we know of, this avoids a potential source of problems (e.g. in collaboration other extensions) at no costs.
