[PATCH] fix COMP_WORDS when completing an empty word

[n+bash]

From: Naïm Favier <n@monade.li>

Currently, typing `cmd flag1  flag2` (note the two spaces), navigating
between the two spaces and hitting Tab produces
`COMP_WORDS=(cmd flag1 flag2)` without inserting an empty word between
flag1 and flag2.

I believe this comes from considering the cursor ("sentinel") as a block
rather than a line, which does not make sense in a completion context,
but might possibly make sense in other contexts?

Note that this aligns with the behaviour of the default readline
completion.
