How do I only commit a subrepo's changes?

I have a master repo, which has some changes I do not want to commit.

I have a subrepo, which has changes that have already been committed.

I want to commit the changes subrepo revision in my master repo, without committing the changes to the files in the master repo.

I cannot seem to do this. I can't commit .hgsubstate, and making a trivial change to a file to commit that does not commit the subrepo changes to the master repo.

Pass the name of the subrepo itself to commit and Mercurial will update .hgsubstate and commit it.

ry4an@four:~$ hg init main
ry4an@four:~$ cd main
ry4an@four:~/main$ hg init sub
ry4an@four:~/main$ echo sub = sub > .hgsub
ry4an@four:~/main$ hg add .hgsub
ry4an@four:~/main$ hg commit
ry4an@four:~/main$ cd sub
ry4an@four:~/main/sub$ echo text > afile
ry4an@four:~/main/sub$ hg commit -Am first-in-sub
adding afile
ry4an@four:~/main/sub$ cd ..
ry4an@four:~/main$ hg status
ry4an@four:~/main$ echo text > dont-commit-me
ry4an@four:~/main$ hg add dont-commit-me
ry4an@four:~/main$ hg status
A dont-commit-me
ry4an@four:~/main$ cat .hgsubstate
0000000000000000000000000000000000000000 sub
ry4an@four:~/main$ hg commit -m 'subrepo only' sub
ry4an@four:~/main$ hg status
A dont-commit-me
ry4an@four:~/main$ cat .hgsubstate
dec5eaa9e22cd0a05cbba3ba02fdb0e1f243e07e sub

Note that the file in main dont-commit-me never got committed, but the .hgsubstate was updated.
