Fixes #108

Changes proposed in this pull request:

  • The final branch of naturaldelta (years > 1) now respects months=True by appending the month count when 0 < num_months < 12, and rolls over to the next year when num_months == 12 — consistent with the years == 1 branch.
  • Updated existing test expectations that encoded the old (incorrect) behavior of ignoring months for multi-year deltas.

Summary

naturaldelta(timedelta(days=int(4.6*365)), months=True) returned "4 years" instead of "4 years, 7 months". A # TODO comment in the source already identified this gap.

Changes

  • src/humanize/time.py: resolve the TODO at the end of naturaldelta; handle num_months == 12 rollover for the years > 1 branch
  • tests/test_time.py: update stale expectations to reflect the corrected output (e.g. "2 years" -> "2 years, 1 month", "27 years" -> "27 years, 5 months")

Testing

pytest tests/test_time.py -q   # 383 passed

Fixes #108

The final branch of naturaldelta (years > 1) always returned a bare
year count even when months=True.  A TODO comment in the code already
identified this gap.  Now, when use_months is True and the remaining
days round to 1-11 months, the output includes the month count
('4 years, 7 months').  When they round to 12 months the year count
is incremented instead, consistent with the years == 1 branch.

Test expectations updated to reflect the corrected output.
