tests: remove unnecessary apostrophe

run-tests: added '--json' functionality to store test result in json file This patch added a new functionality '--json'. While testing, if '--json' is enabled then test result data gets stored in newly created "report.json" file in the following format. testreport ={ "test-success.t": { "result": "success", "time": "2.041" } "test-failure.t": { "result": "failure", "time": "4.430" } "test-skip.t": { "result": "skip" "time": "3.754" } } Otherwise, if '--json' is enabled but json module was not installed then it will raise an error "json module not installed". This "report.json" file will further accessed by html/javascript file for graph usage.

changegroup: rename bundle-related functions and classes Functions like getbundle and classes like unbundle10 really manipulate changegroups and not bundles. A HG10 bundle is the same as a changegroup plus a small header, but this is no longer the case for a HG2X bundle, so it's better to separate the names a bit.

comments: describe ancestor consistently - avoid 'least common ancestor' "best" is as defined by mercurial.ancestor.ancestors: furthest from a root (as measured by longest path).

rebase: improve description of --base No Mercurial DAG has ever (!) been drawn in a way where 'up to' would apply. Instead, describe deliberatey vague and informal instead of seemingly precise but not describing the essentials: rebase the tree around the specified changeset without ancestors of dest

dagutils: fix docstrings for singleton internalize/externalize

cmdutil: avoid the confusing name 'patch' for a matcher

fedora: remove sample.hgrc from shipped files sample.hgrc was long obsolete and was removed in 63ed188e3fc7.

config: propose some sample global config file An example of what could be suggested to the user as a global config file. Trying to be conservative here, and only suggesting the safest possible extensions. In addition to the user-level extensions, the blackbox extension is something a sysadmin might reasonable want to enable for every repo on the system.

config: give more fine-tuned sample hgrcs to this command The hgrc for user config is typically different from the hgrc at the system-wide or repository level. This patch provides different sample hgrcs for each level. Sometimes when copying repos around, the copy or the original don't have a default path yet, so at least for `hg config -l`, this ought to provide a more reasonable default and suggestions of what typically goes there. The actual sample configs go in the config.py file, to minimise clutter. In order to avoid an unnecessary import, the corresponding import for this dictionary is at the file level.
