largefiles: notice dirty large files in a subrepo Summary and commit use dirty() to check the status of a subrepository, so this overrides dirty() in the subrepo in the same manner as status() to check the large files instead of their standins. Previously, if only a large file was changed in a subrepo, summary in the top level repo would not report the subrepo was dirty and commit -S would report nothing changed. If any type of file was changed in the top repo and only a large file in the subrepo, commit -S would not commit the changes to the subrepo.

largefiles: fix status -S reporting of subrepos (issue3231) Wrapping the status command will only invoke overridestatus() and set the lfstatus field for the top level repository. Wrapping the status function is required to set the field on child repositories. Previously, status -S would report large files in a subrepo as '?' regardless of their actual states, and was inconsistent with what status would report from within that subrepo.

i18n: use locale insensitive format for datetimes as intermediate representation (issue3398) on some non "en" locale environments, "hg convert" is aborted, because "util.parsedate()" fails. it fails in "memctx.__init__()" called by "putcommit()" of "convert". in "hg convert", datetimes gotten from source repository are usually formatted by "util.datestr()" with default format "%a %b %d %H:%M:%S %Y %1%2". but on some environments, "%a" and "%b" may cause locale sensitive string, and such string may cause parse error in "util.parsedate()". this path uses "%Y-%m-%d %H:%M:%S %1%2" as intermediate representation format for datetimes, because it consists only of locale insensitive elements. datetimes in above format are only used for passing them from conversion logic to memctx object, so it doesn't have to be formatted by locale sensitive one. this patch just avoids locale sensitivity problem of "datestr()" and "parsedate()" combintion.

alias: fix shell alias documentation (issue3374) Described behaviour was the one before shell alias argument handling was reworked by f853873fc66d mid-2010.

test-convert-svn-sink: add helper to smooth svn xml output svnxml.py parses "svn log --xml" output and prints the attributes shared among all tested svn versions. This fixes the test with svn 1.7. Tested with svn 1.6.12 and 1.7.4.

convert/svn: make svn sink work with svn 1.7 "svn add file" now fails if "file" is already tracked. To filter them we have to mirror the svn manifest in the sink. Tested with svn 1.6.12 and 1.7.4.

docs: don't use :hg: at the beginning of lines in notes (issue3397) It seem like docutils 0.8 interpret ':hg:`command`' roles at the beginning of indented lines in '.. note::' directives as a field that is an invalid argument to the directive. It fails with 'Error in "note" directive: invalid option block.' Docutils 0.7 accepted this arguably incorrect markup. Reflowing the text makes the problem go away. A leading '\ ' could perhaps also be used to mask the problem.
