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()
