Tracker3 ignores custom ‘text-allowlist’ extensions list
See https://discourse.gnome.org/t/tracker3-ignores-custom-text-allowlist-extensions-list/6813:
We provide a text-allowlist
gsetting which confusingly doesn't provide full control over which text files are indexed. The MIME type rule in /usr/share/tracker3-miners/extract-rules/15-text.rule has precidence and only allows through text/plain
and text/markdown
mimetypes.
At minimum we need to document this clearly, and perhaps we should also expand the list of allowed MIME types.
