Status fails when dirstate lists unknown parent #36

However, Mercurial, if there's a repository with bad parent revision in 
dirstate, is still able to proceed, with a warning:

$hg status
warning: ignoring unknown working parent 58d1c0570390!
M ...

It seems it dumps dirstate state for Added, Removed and Merged, and reports 
rest (Normal files) as Modified.

I don't see value in such a status, so ignoring bad parent doesn't seem to be 
an option. Instead, this might be a good item to check in a dedicated 
'verify/validate/check' operation
