still use old variable names when running hooks. dropped by accident. we set HG_FOO (new name) and FOO (old name). plan is to drop old names after 0.9.

adding foo
adding bomb
adding a.c
adding dir/a.o
adding dir/b.o
! a.c
! dir/a.o
! dir/b.o
? .hgignore
a.c: unsupported file type (type is fifo)
! a.c
