The gen-cli-reference binary was accumulating extra blank lines after
the <!-- AUTOGEN END --> marker on each regeneration because it
preserved all content after the marker (including leading whitespace)
and then added its own newlines.
Fix: Trim leading whitespace from hand-curated content before appending.
Also regenerated cli-reference.md to remove accumulated blank lines.
Closes pdftract-1j0f8
The bead description mentioned compile errors in hash.rs from API drift,
but those errors were either already fixed or misattributed. The API usage
was already correct:
- compute_fingerprint already takes 3 arguments with source
- len() already propagates Result with ?
- read_at method already used correctly
- Catalog fields accessed via trailer correctly
Only cleanup: removed unused std::fs::File and std::io imports.
Verification: notes/bf-4mkhv.md
- Add worked example to Glyph struct showing all 11 fields
- Add worked example to Span struct showing all 10 fields
- Examples use rust,no_run for internal dependencies
- cargo doc passes with docs.rs feature set
- Verification note added at notes/pdftract-3eohy.md
