subrepos: abort commit by default if a subrepo is dirty (BC)
This changeset flips the default value of ui.commitsubrepos setting
from True to False and adds a --subrepos flag to commit.
The commit, status, and diff commands behave like this with regard to
recusion and the ui.commitsubrepos setting:
| recurses | recurses
| by default | with --subrepos
--------+---------------+----------------
commit: | commitsubrepo | True
status: | False | True
diff: | False | True
By changing the default from True to False, the table becomes
consistent in the two columns:
* without --subrepos on the command line, commit will abort if a
subrepo is dirty and status/diff wont show changes inside subrepos.
* with --subrepos, all three commands will recurse.
A --subrepos flag on the command line overrides the config settin.g
$ hg init
$ echo a > a
$ hg ci -Am0

$ hg -q clone . foo
$ touch .hg/store/journal
$ echo foo > a
$ hg ci -Am0
abort: abandoned transaction found - run hg recover!

$ hg recover
