test-non-interactive-wsgi: make output deterministic

hgweb: fix error in 38170eeed18c and introduce test for change

ui: add environ property to access os.environ or wsgirequest.environ The property returns os.environ by default, and is propagated by ui.copy. During hgweb processing, ui.environ is set to the proper WSGI-request environment, as contained in wsgirequest.environ. For CGI, this is the same as os.environ. The property is meant to be read-only, as with os.environ (generally).

relink: wrap long lines in docstring

test-convert-filemap: test improved filtering algorithm

convert: make filemap favor most specific filtering rule A filemap like: exclude "doc" include "doc/foo.txt" will now preserve doc/foo.txt and exclude everything else in doc/.

run-tests: set --home when building with distutils If home was set in ~/.pydistutils.cfg, the tests could not run. This overrides any home setting by supplying --home="" on the command line.
