rollback: add dry-run argument, emit transaction description [ original upstream message ]

Do not bother about detecting extension path in demo Detecting and showing the path to a keyword extension in a non-standard place only made sense while keyword.py was not shipped with Mercurial. The test output has changed because we do not have a spurious space at eol anymore.

keywords: build a new templater to work around caching interaction

Tests with spaces in paths This allows most tests to succeed with ./run-tests.py --tmpdir='/tmp/hg test' and introduces other tests for spaces and shell quoting [ original upstream message ]

(0.9.2compat) get applicable changes from default

(stable) merge Even though this is a fake standalone branch, we do not include the patch that removed extension path detection in kwdemo.

Make kwdemo less verbose 1) Set the branchname always silently with dirstate.setbranch(). We create a branch so that testing the {branches} template does not come up empty. But kwdemo is hardly the place to inform the user by inference why {branches} is empty on the default branch. "demobranch" is ascii and cannot be changed, so using the internal command instead of commands.branch() is safe. 2) Do not show full path to temporary directory (distracting long lines on Mac OS X). 3) No special debug output. Output only related to keyword, no internals like unsetting of commit hooks etc.
