tests: prepare rebase test for wc parent preservation In the way to solving issue3813 we'll preserve the working directory parent after the rebase. Multiple rebases test expect the working directory parent to be tip after rebase. We patches them before the actual change to prevent confusion.

tests: test-gendoc.t checks if anything was translated This would triggered when the variable would be set wrong again.

tests: really test translations for rst syntax errors (issue4003) The variable LC_ALL did not work, use LANGUAGE instead. Before this patch, the original language C was generated (and tested) in every run.

i18n: fix wrong rst syntax Fix syntax errors like wrong indentation and invalid quotation. All errors preventing to generate valid html documentation (by gendoc.py) are fixed.

i18n-ru: fix the language team field Having this at the default value caused some versions of msgfmt to give fatal errors.

commands: refactor 'serve', extract the http service class

largefiles: refactor basestore, extract _gethash method

largefiles: make the protocol hack for replacing heads with lheads more precise Before the hack would replace 'heads' with 'lheads' no matter where it occured in a batch command string. Instead we will use a regexp to more carefully only match the 'heads' commands.

mq: refactor usage of repo.branchmap().iteritems() with itervalues()
