subrepo: return both mapping directions from gitbranchmap

subrepo: strip gitcommand output

sshrepo: don't use readline() on the stderr pipe For some reason, the stat/readline dance suppressed lines following the first in PyPy 1.4.

test-demandimport.py: PyPy support The stringification of sys.stderr is different in PyPy: $ pypy -c 'import sys; print sys.stderr' <open file '<fdopen>', mode 'w' at 0x00a42080> $ python -c 'import sys; print sys.stderr' <open file '<stderr>', mode 'w' at 0x10025a270> The test will now ignore the exact value between the angle brackets.

demandimport: change default for level from None to -1 The Python default for this function is -1, indicating both relative and absolute imports should be used.[1] Previously, we relied on the Python VM not passing level when such semantics were requisted. This is not the case for PyPy, however, where a level of -1 is always passed to __import__. [1] <http://docs.python.org/library/functions.html#__import__>

export: flush the file pointer between patches

test-clone-failure.t: fix unification oversight Prior to unification, the test contained an 'echo $?' line. This line was removed during unification, but the 'echo 255' line that faked it when FIFO support is absent was not.
