verify: check the subrepository references in .hgsubstate...
verify: check the subrepository references in .hgsubstate While hopefully atypical, there are reasons that a subrepository revision can be lost that aren't covered by corruption of the .hgsubstate revlog. Such things can happen when a subrepo is amended, stripped or simply isn't pulled from upstream because the parent repo revision wasn't updated yet. There's no way to know if it is an error, but this will find potential problems sooner than when some random revision is updated. Until recently, convert made no attempt at rewriting the .hgsubstate file. The impetuous for this is to verify the conversion of some repositories, and this is orders of magnitude faster than a bash script from 0..tip that does an 'hg update -C $rev'. But it is equally useful to determine if everything has been pulled down before taking a thumb drive on the go. It feels somewhat wrong to leave this out of verifymod (mostly because the file is already read in there, and the final summary is printed before the subrepos are checked). But verifymod looks very low level, so importing subrepo stuff there seems more wrong.
