Thank goodness for "hide whitespace"

Seems fine. Probably no need to keep the old code around. If you do, I'd add a comment about what it used to do, and why you took it out.

I'm seeing  'error: unknown type name 'constexpr' with the UnRAR update.

It seems that C++11 must be enabled for 'constexpr' keyword to be recognized.

I'm still trying to figure out why GitHub's Mac pipeline is failing to use C++11 (and failing the the build).
Works fine on our Mac arm64 universal binary static-dependencies .pkg build, and also fine on our Mac x64 building just for x64...

Because it includes rar.hpp, the UnRAR iface also uses C++11 features.
UnRAR logic replaces directory symlinks found within archive file entry
file paths with actual directories by deleting them after they're
extracted.

Unfortunately, this logic extends to deleting existing directories if you
set the `DestName` instead of the `DestPath` in this API:

  rc = RARProcessFile(hArchive, RAR_EXTRACT, NULL, destFilePath);

In the future UnRAR may change to disable the `LinksToDirs()` feature
if using the `DestName` parameter. In the meantime, this commit
completely disables it for our use case.
This is a cherry-pick of commit 24f225c

Modification to unrar codebase allowing skipping of files within
Solid archives when parsing in extraction mode, enabling us to skip
encrypted files while still scanning metadata and potentially
scanning unencrypted files later in the archive.
Prevent allocating more than 1GB regardless of what is requested.
RAR dictionary sizes may not be larger than 1GB, at least in the current
version.

This is a cherry-pick of commit 9b444e7

Silly me. It was unrar_iface that was failing to build, because it includes rar.hpp which requires C++11 features. Fixed with a8fdb2b

Now just to watch the test pipelines...

Testing looking good after that last fix.
