setup: hide octal literals inside strings so they're portable (
issue4554)
revset: avoid returning duplicates when returning ancestors
Before this patch, _revancestors were giving false result when a revision was
duplicated in the input. Duplicated entry are rare but may happen when using the
`%lx` notation internally.
This series has no visible impact on the performance of the function according
to benchmark.
revset: use an iterator instead of a dequeue in ancestors()
The dequeue was actually just used to be able to pop value one at a time.
Building the dequeue means we are reading all the input value at once at the
beginning of the evaluation. This defeat the lazyness of revset.
We replace the deque with iterator usage for the sake of simplicity and
lazyness.
This provide massive speedup to get the first result if the input set is big

revset: return early when revs is empty
By introducing an early return in _revancestors() when revs is empty,
we make it so inputrev is never None, which simplifies the subsequent
code.
revset: rename 'revsnode' to 'inputrev' in ancestors
We usually use 'node' for variable containing 20 bytes hash. There is nothing
nodish in this variable, so we rename it to "inputrev" as it old the next entry
of the iteration.
revset: make generatorset.__nonzero__ lazy
The 'for r in self:' call could trigger full consumption of the generator while
we only need a single value. We also fast path if a single value got already
computed. See inline comment for more details.
This provide massive speedup for lazy operation using boolean testing.

tests: test that we can convert to manifestv2 with clone
This just adds a test to ensure that we can convert a manifestv1 repo to a
manifestv2 repo (for future commits only) by means of a local clone.
requires: move requires file writing func from localrepo to scmutil
The logic to read a requires file resides in scmutil, so it's only logical that
the logic to write the file should be there too.
And now I've typed logic too many times it no longer looks like a word.
Logically.
histedit: fix test-histedit-edit on vfat
test-histedit-edit was broken because it relied on the HGEDITOR script being
executable. Instead, lets just execute 'sh' and pass it the script to run. This
seems to be the pattern followed in other tests.
