In regex 1.10.0, the \b{start-half} and \b{end-half} assertions were
introduced to improve how the -w/--word-regexp flag handles patterns
containing non-word characters. While ripgrep's CLI help text was
updated to mention this syntax during the lexopt transition (082245d),
it omitted the rationale, potentially leaving users puzzled by this
casual mention of a highly specific, non-standard regex feature.
Furthermore, GUIDE.md was still outdated, incorrectly claiming
that -w wraps patterns in standard \b boundaries,
further compounding the inconsistency and potential for confusion.
This commit updates GUIDE.md to reflect the actual underlying regex
employed by ripgrep when the -w/--word-regexp flag is used.
It also adds a brief explanation to both the guide and the manpage
acknowledging the non-standard nature of these half-boundary markers,
and explaining what they're meant for.

ripgrep core
This is the core ripgrep crate. In particular, main.rs is where the main
function lives.
Most of ripgrep core consists of two things:
- The definition of the CLI interface, including docs for every flag.
- Glue code that brings the
grep-matcher,grep-regex,grep-searcherandgrep-printercrates together to actually execute the search.
Currently, there are no plans to make ripgrep core available as an independent library. However, much of the heavy lifting of ripgrep is done via its constituent crates, which can be reused independent of ripgrep. Unfortunately, there is no guide or tutorial to teach folks how to do this yet.
