tweaks: move two checks plus corresponding calls to a better place

It was silly to check again specifically for <Del> and <Bsp> after
any possible keystroke had been handled.  It was an anomaly.

This makes the tail of do_deletion() similar to the tail of inject().

(That sometimes the current line is redrawn twice is acceptable -- how
often does one type <Backspace> while having Shift-selected something?
Normally one wouldn't, because it would cancel the selection, so it's
fine to accept some inefficiency for this case.)
