This basically removes hidden 'all() &' from union/negation of filters. To
achieve that, I have two options: 1. add separate evaluation path (like the
one this commit introduced), or 2. wrap "all()" revset to override predicate
as Box::new(|_| true) function. I took the former since it's less ad-hoc.
We can add an explicit RevsetExpression node to branch between evaluate()
and evaluate_predicate(), but I don't think it would simplify the
implementation at this point. We might need such node if we want to resolve
"all()" at resolve_symbols(). It might be even better to extract a subset of
RevsetExpression enum, which only contains evaluatable nodes.
The cost of 'all() &' isn't significant for most filters. '~merges()' is
the exception. For jj repo,
revsets/:v0.3.0 & (author(martinvonz) | committer(martinvonz))
--------------------------------------------------------------
base 1.06 11.2±0.04m
new 1.00 10.5±0.05m
revsets/~merges()
-----------------
base 1.69 750.0±8.47µ
new 1.00 444.1±3.50µ
This command is similar to Mercurial's revset benchmarking command. It
lets you pass in a file containing revsets. I also included a file
with some revsets to test on the git.git repo. I put it in `testing/`,
which doesn't seem perfect. I'm happy to hear suggestions for better
places, or we can move it later if we find a better place.
Note that these tests don't clear caches between each run (or even
between tests), so revsets that rely on filtering commit data that's
not indexed appear faster than they typically are in reality.
I ran an upgraded Clippy on the codebase. All the changes seem to be
about using variables directly in format strings instead of passing
them as separate arguments.
This is a followup to f4b175a8. When debugging `fake-editor`
failures, it is often useful to distinguish empty files,
files consisting of a single "\n" and so on.

correctly, it won't have any legal effect, but maybe it still helps
reduce concerns from contributors (though I haven't heard any

This adds a `next invocation` command to `fake-editor` that ignores the
rest of the script for *this* invocation, but overwrites the script
with whatever follows `next invocation`.
This is useful to test commands that invoke `fake-editor` several times,
especially the `jj split` command.
