revset: add startdepth limit to ancestors() as internal option
This is necessary to implement the set{gen} (set subscript) operator. For
example, set{-n} will be translated to ancestors(set, depth=n, startdepth=n).
https://www.mercurial-scm.org/wiki/RevsetOperatorPlan#ideas_from_mpm
The UI is undecided and I doubt if the startdepth option would be actually
useful, so the option is hidden for now. 'depth' could be extended to take
min:max range, in which case, integer depth should select a single generation.
ancestors(set, depth=:y) # scan up to y-th generation
ancestors(set, depth=x:) # skip until (x-1)-th generation
ancestors(set, depth=x) # select only x-th generation
Any ideas are welcomed.
# reverse(ancestors(tip)) using hg repo

Push should provide a hint when both 'default' and 'default-push' not set:
$ cd c
$ hg push --config paths.default=
abort: default repository not configured!
(see 'hg help config.paths')

$ cd ..
Push should push to 'default' when 'default-push' not set:

Push should push to 'default-push' when set:

But push should push to 'default' if explicitly specified (issue5000):
$ hg --cwd b push default
pushing to $TESTTMP/a (glob)
searching for changes
no changes found

Push should push to 'default-push' when 'default' is not set
$ hg -q clone a push-default-only
$ cd push-default-only
$ rm .hg/hgrc
$ touch foo
$ hg -q commit -A -m 'add foo'
$ hg --config paths.default-push=../a push

Pushing to a path that isn't defined should not fall back to default
$ hg --cwd b push doesnotexist
abort: repository doesnotexist does not exist!

:pushurl is used when defined
$ hg -q clone a pushurlsource
$ hg -q clone a pushurldest
$ cd pushurlsource

Invalid :pushrev raises appropriately
$ hg --config 'paths.default:pushrev=notdefined()' push
pushing to file:/*/$TESTTMP/pushurlsource/../pushurldest (glob)
hg: parse error: unknown identifier: notdefined
[255]
$ hg --config 'paths.default:pushrev=(' push
pushing to file:/*/$TESTTMP/pushurlsource/../pushurldest (glob)
hg: parse error at 1: not a prefix: end
