Panic with .\ directory prefix

[edeca]

When using YARA-X 0.12.0 a panic is generated if the path starts with .\. This is how PowerShell auto-completes folder names relative to the current directory. Example:

PS C:\<my_user_directory>\yara> yr scan -r "C:\<path>\rule.yar" .\samples\
thread '<unnamed>' panicked at C:\Users\runneradmin/.cargo\registry\src\index.crates.io-6f17d22bba15001f\globwalk-0.9.1\src\lib.rs:381:78:
called `Result::unwrap()` on an `Err` value: StripPrefixError(())
note: run with `RUST_BACKTRACE=1` environment variable to display a backtrace

Also affects Linux:

-> % ./yr scan -r rule.yar ./samples
thread '<unnamed>' panicked at /home/runner/.cargo/registry/src/index.crates.io-6f17d22bba15001f/globwalk-0.9.1/src/lib.rs:381:78:
called `Result::unwrap()` on an `Err` value: StripPrefixError(())
note: run with `RUST_BACKTRACE=1` environment variable to display a backtrace

Testing:

• .\samples - does not work
• .\samples\ - does not work
• samples\ - works
• samples - works
• ..\yara\samples\ - works

All the working examples are fine with the backslash substituted for a forward slash (on Windows), so the only difference is the .\.

This is a known issue in the globwalk crate.
