hook: add a generic hook after transaction has been closed
We are adding generic hooking for all transactions. We may have useful
information about what happened during the transaction, user of the transaction
should have filled the 'hookargs' dictionnary of the transaction. This hook is
simple because it has no power to rollback the transaction.
#require execbit
$ hg init
$ echo a > a
$ hg ci -Am'not executable'
adding a
$ chmod +x a
$ hg ci -m'executable'
$ hg id

Make sure we notice the change of mode if the cached size == -1:
$ hg rm a
$ hg revert -r 0 a
$ hg debugstate
n 0 -1 unset a
$ hg status
M a
$ hg up 0
1 files updated, 0 files merged, 0 files removed, 0 files unresolved
$ hg id

$ test -x a && echo executable -- bad || echo not executable -- good
not executable -- good
