ungoogled-chromium/patches/extra/ungoogled-chromium/default-to-https-scheme.patch

# Default to https for (non-standard) URLs without scheme.
#
# This patch handles URLs like user:pass@example.com and trims scheme in suggestions if it is implicit.
# URLs entered in md_bookmarks (chrome://bookmarks) will also get https:// prefix.
#
# Note that there is a small hack in AutocompleteInput::HasHTTPScheme: we check kHttpsScheme instead.
# All other changes in omnibox were made to preserve old behavior.
