issue2444)
This file is not critical for hg, so we can safely

$ hg up
deadbeef
note: possible conflict - X was renamed multiple times to:

of just referencing the global table, thereby enabling reuse
for extension command tables.
subrepo: abort instead of pushing/pulling to the repo itself

path can be found.
