patches: 0007 fix hl-line-mode blocking SelectedTextChanged

hl-line-mode (and similar) bumps BUF_MODIFF via text property
changes on every cursor movement. The else-if structure caused
the modiff branch to fire (skipping ValueChanged correctly) but
also blocked the cursor-move branch (SelectedTextChanged).

Fix: use textDidChange flag to decouple the two branches.
ValueChanged and SelectedTextChanged remain mutually exclusive
for real edits, but SelectedTextChanged now fires when only
text properties changed.
