Thanks for the review!

Agreed.

The notmuch header parser converts the tabs in header folding to spaces,
gmime keeps them as tabs. AFAICT that is the only difference between
headers indexed by notmuch and gmime, and causes tests to fail. So we do
the tabs to spaces conversion here to produce same output from cli. This
patch just does the minimal change required for tests to pass; other
changes might be good too, but they were not relevant for this series.

BR,
Jani.
