Glob panicked because of an out-of-bounds error on the pattern

I tried to use a pretty basic pattern, and got the following crash (ran with RUST_BACKTRACE=1):

thread 'main' panicked at C:\Users\cleme\.cargo\registry\src\index.crates.io-6f17d22bba15001f\glob-0.3.1\src\lib.rs:218:32:

Context:

• Glob v0.3.1
• Windows 11 23H2 (not WSL)
• CWD on D: drive (not C:)
• Rust v1.74.0

EDIT: Problem doesn't appear when I use \*.custom*\* instead of \\*.custom*\* (removing one of the lead backslashes)

Reproduce the panic on Windows with the reported doubled-leading-backslash pattern, then inspect glob_with at src/lib.rs:218 using the stack trace as the starting point. Add a regression test for this pattern and verify that glob no longer panics.
