cat: move most of the implementation into cmdutils.cat() This will allow access to the reusable parts from subrepos, similar to add(), forget(), etc.

tests: mark test in tests/test-help.t as contingent on gettext being available

setup.py: fix C extension compilation issue with OS X 10.9 and Xcode 5.1

color: add effect to the template symbol table Previously, words like 'red' had to be protected by quotes before passing to the label template function. Now, we add color effects to the symbol table so that commands like, $ hg log -r . -T "{label(red, node|short)}\n" can work without the need for quoting.

amend: invoke editor forcibly when "--edit" option is specified 422981492ace introduces "--edit" option into "hg commit", but it doesn't work for "hg commit --amend", because 422981492ace prepares for editor invocation only around "commitfunc()" internal function, which is used only for temporary amend commit by "cmdutil.amend()". Actual commit message editing is executed in "cmdutil.amend()". This patch invokes editor forcibly when "--edit" option is specified for "hg commit --amend", even if commit message is specified explicitly by "--message" or "--logfile". This patch also removes useless handling for commit message and editor invocation around "commitfunc()" internal function.

commit: abolish useless "--force-editor" internal option for "hg commit" "--force-editor" option for "hg commit" has been useless since 12721a20ed30, which makes "commands.tag()" invoke "cmdutil.commit()" directly instead of "commands.commit()" with "--force-editor" internal option. This patch abolishes useless "--force-editor" internal option for "hg commit".

subrepo: return non-zero exit code when a subrepo push doesn't succeed

debugrevlog: use unfiltered view for changelog

debugrevlog: format columns (more) nicely when dumping index data

branchmap: log events related to branch cache The blackblox log will now contain log events when the branch caches are updated and written.

tags: log events related to tags cache We now log when .hg/cache/tags data is built from scratch by reading manifests and when the file is written.

histedit: save manually edited commit message into ".hg/last-message.txt" Before this patch, manually edited commit message for "message" command in histedit-ing is not saved into ".hg/last-message.txt" until it is saved by "localrepository.savecommitmessage()" in "localrepository.commit()". This may lose such commit message, if unexpected exception is raised. This patch saves manually edited commit message for "message" comand in histedit-ing into ".hg/last-message.txt" just after user editing. This is the simplest implementation to fix on stable. Editing and saving commit message should be centralized into the framework of "localrepository.commit()" with "editor" argument in the future. This patch uses repository wrapping class for exception raising before saving commit message in "localrepository.commit()" easily and certainly, because such exception requires corner case condition.

rebase: tell when reopening a closed branch head Give same 'reopening closed branch head X' message as commit gives.

dirstate: inline local finish function Having it as a local function adds no value.
