stabletailgraph: add test cases challenging the open merge stack
This adds three more complex test cases with situations requiring tricky
state update in the stack-based iteration (arriving soon).
Create an empty repo:
$ hg init a
$ cd a
Try some commands:
$ hg log
$ hg grep wah
[1]
$ hg manifest
$ hg verify -q
Check the basic files created:
$ ls .hg
00changelog.i
cache
requires
store
wcache
Should be empty (except for the "basic" requires):
$ ls .hg/store
requires
Poke at a clone:
$ cd ..
$ hg clone a b
updating to branch default
0 files updated, 0 files merged, 0 files removed, 0 files unresolved
$ cd b
$ hg verify -q
$ ls .hg
00changelog.i
branch
cache
hgrc
requires
store
wcache
Should be empty (except for the "basic" requires):
$ ls .hg/store
requires
$ cd ..
