Backed out changeset cfa477946181824f4c769580ebf59710090ba08a
Only printenv was changed, not the actual execution of hooks.
And not setting an empty value might cause problems on platforms
which can't always remove variables from the environment.
# simple script to be used in hooks
# copy it to the current directory when the test starts:
#
# cp "$TESTDIR"/printenv.py .
#
# put something like this in the repo .hg/hgrc:
#
# [hooks]
# changegroup = python ../printenv.py <hookname> [exit] [output]
#
# - <hookname> is a mandatory argument (e.g. "changegroup")
# - [exit] is the exit code of the hook (default: 0)
# - [output] is the name of the output file (default: use sys.stdout)
# the file will be opened in append mode.
#
