bundle2: make the "hgtagsfnodes" part advisory
This bundle2 part is about helping the client to warms its cache. There is no
reason for it to be mandatory.
So we mark it advisory.
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 ..
