subrepo: bare git repos considered dirty
Currently, if there is a bare git subrepo, but it is at the "right"
revision, calling dirty() will error because diff-index does not work
on bare repos. This patch makes it so bare subrepos are always
considered dirty.
dispatch: use the request to store the ui object
and check if we got one before creating.
note that the contents of the ui object might change after
dispatch() returns (by options passed through --config for example),
to ensure it doesn't, pass a copy() of it.
dispatch: wrap dispatch related information in a request class
currently only stores the arguments.
patch: restore the previous output of 'diff --stat'
Restore the previous diffstat behaviour of scaling by the maximum number of
changes to a single file. Changeset
f03f08240c32 modified the diffstat to be
scaled by the total number of changes. This seems to have been unintentional.
