mergestate: raise structured exception for unsupported merge records
We're going to catch this exception in 'hg summary' to print a better error
message.
This code is pretty untested, so there are no changes to test output. In
upcoming patches we're going to test the output more thoroughly.
Create an empty repo:
$ hg init a
$ cd a
Try some commands:
$ hg log
$ hg grep wah
[1]
$ hg manifest
$ hg verify

Check the basic files created:
$ ls .hg
00changelog.i
requires

Should be empty:
$ ls .hg/store
Poke at a clone:
$ cd ..
$ hg clone a b
updating to branch default
