flags: account for flag change when tracking rename relevant to merge
There are some logic filtering rename to the one relevant to the merge. That
logic was oblivious of flag change, leading to exec flag being dropped when
merged with a renamed.
There are two others bugs affecting this scenario. This patch fix the was where
there is not modification involved except for the flag change. Fixes for the
other bug are coming in later changesets.

# Oxidized Mercurial This project provides a Rust implementation of the Mercurial (`hg`) version control tool. Under the hood, the project uses [PyOxidizer](https://github.com/indygreg/PyOxidizer) to embed a Python interpreter in a binary built with Rust. At run-time, the Rust `fn main()` is called and Rust code handles initial process startup. An in-process Python interpreter is started (if needed) to provide additional functionality. # Building This project currently requires an unreleased version of PyOxidizer (0.7.0-pre). For best results, build the exact PyOxidizer commit as defined in the `pyoxidizer.bzl` file: $ git clone https://github.com/indygreg/PyOxidizer.git $ cd PyOxidizer $ git checkout <Git commit from pyoxidizer.bzl> $ cargo build --release Then build this Rust project using the built `pyoxidizer` executable:: $ /path/to/pyoxidizer/target/release/pyoxidizer build If all goes according to plan, there should be an assembled application under `build/<arch>/debug/app/` with an `hg` executable: $ build/x86_64-unknown-linux-gnu/debug/app/hg version Mercurial Distributed SCM (version 5.3.1+433-f99cd77d53dc+20200331) (see https://mercurial-scm.org for more information) Copyright (C) 2005-2020 Matt Mackall and others This is free software; see the source for copying conditions. There is NO warranty; not even for MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. # Running Tests To run tests with a built `hg` executable, you can use the `--with-hg` argument to `run-tests.py`. But there's a wrinkle: many tests run custom Python scripts that need to `import` modules provided by Mercurial. Since these modules are embedded in the produced `hg` executable, a regular Python interpreter can't access them! To work around this, set `PYTHONPATH` to the Mercurial source directory. e.g.: $ cd /path/to/hg/src/tests $ PYTHONPATH=`pwd`/.. python3.7 run-tests.py \ --with-hg `pwd`/../rust/hgcli/build/x86_64-unknown-linux-gnu/debug/app/hg
