plan9: add missing source entries to proto

Merge stable

tests: fix incorrect markup of continued lines of sh commands

check-code: 'printf \0' is apparently fine - accept it in check-code Nobody complained over '\0' in test-eol.t. The too strict check becomes a problem when this check is applied to more lines.

tests: solaris sh can not negate exit status with '!'

tests: hide diff -u saying 'No differences encountered' on solaris

tests: ^ must be quoted when used on solaris sh The check was broken when it was introduced in 6e4cf8319f54.

tests: remove test-pull-pull-corruption2.t This test gave random failures on slow machines (solaris). The test was added in 6f6e210b38cf as a test case from issue148. It did however require manual setup: The attached script creates such a corruption (you have to add a "import time; time.spleep(3)" in localrepo.addchangegroup before the changegroup manifest are written for example. The test as it is has thus no value as automatic test case. The necessary sleep could be added by a hook, but test-pending.t already tests that.

tests: remove race in test-pull-pull-corruption.t The output from the background process was not always interleaved "correctly" with output from the foreground process.
