Greptile SummaryThis PR corrects reconstruction of long option references split across physical help-text lines and refreshes the Pip-generated documentation and service implementation.
Confidence Score: 5/5The PR appears safe to merge, with the wrapped-option fix constrained by parser boundaries and supported by focused regression coverage. No actionable correctness, security, or repository-rule violation remains in the reviewed changes.

pip wraps option references across help lines. Joining every physical line with a space produced incorrect generated documentation such as --python- version, --find- links, and --ignore- installed.
The shared description accumulator now rejoins a long option reference split at an internal hyphen after confirming that the next line is description text. Ordinary words, prose hyphens, standalone --, and new option declarations retain their boundaries. Coverage includes captured pip 25.3 help and explicit positive/negative cases.
Authoritative Linux pip 24.0 output from run 34768982811 is incorporated in 2b7c6e4. The affected option comments now retain exact flag names; all 14 generated pip wrappers also use the shared ConfigureAwait(false) template fix. No option types, attributes, public API, command coverage, or Markdown documentation changed.
Validation:
Remaining integration regeneration for the shared await template is tracked in #4848. Current-head CI and review remain required before merge.
Closes #4738
