The error is already ignored when the .hg directory is read-only,
so this is only fair. (the python hg is silent on readonly fs, too)

$ hg init repo0

Command works on an empty repo
$ hg show work
Single draft changeset shown
$ echo 0 > foo
$ hg -q commit -A -m 'commit 0'
$ hg show work
@ 9f17 commit 0
Even when it isn't the wdir
$ hg -q up null
$ hg show work
o 9f17 commit 0
Single changeset is still there when public because it is a head
$ hg phase --public -r 0
$ hg show work
o 9f17 commit 0
A draft child will show both it and public parent
$ hg -q up 0
$ echo 1 > foo
$ hg commit -m 'commit 1'
