[BUG] New clone of repo shows modification to `pure2-regex_10_escapes.cpp.execution`

[bluetarpmedia]

Tested on Windows 11 and Ubuntu 22.04:

A new, fresh clone of the cppfront repo shows a change to pure2-regex_10_escapes.cpp.execution.

Repro:

$ git clone https://github.com/hsutter/cppfront.git
$ cd cppfront
$ git status
On branch main
Your branch is up to date with 'origin/main'.

Changes not staged for commit:
  (use "git add <file>..." to update what will be committed)
  (use "git restore <file>..." to discard changes in working directory)
        modified:   regression-tests/test-results/msvc-2022-c++latest/pure2-regex_10_escapes.cpp.execution

no changes added to commit (use "git add" and/or "git commit -a")

This message also appears in CI regarding the file:

warning: in the working copy of 'regression-tests/test-results/gcc-14-c++2b/pure2-regex_10_escapes.cpp.execution', CRLF will be replaced by LF the next time Git touches it

However, I'm not convinced the problem is with the line endings because other .execution files appear to have CRLF endings.

Instead I'm wondering if there's something in the file itself which is causing a problem. The GitHub preview stops printing the line numbers after line 38:

I had a look in Notepad++ and it shows the \f Form Feed, \a Bell and \e Esc characters, so maybe that confuses the GitHub preview.

This regex tests if escapes for special characters are handled properly. The main problem is the automatic change of the line ending of github. I updated the result file now several times and also got a bug report via mail.

I think I should just simple remove this test.

[DyXel]

For those tests you should probably not output what is being matched but rather if it was matched, and integer ranges.

[MaxSagebaum]

I got the idea that I can just sanitize the outputs. I created a branch. #1224

[hsutter]

I've been having problems with this file too and I thought my local git was corrupt -- it would not let me discard the "changes" and as a workaround I had to re-commit the file, otherwise I couldn't even change branches.

Whew! It's just the file content, that's good news.

Yes if we could fix this that would be grand. 🙏

The bugfix branch is ready to merge.
