in the first call of 'completefunc'
Solution: Call check_cursor() after calling 'completefunc' (zeertzjq)

Problem: complete_info() returns wrong order of items
(after v9.0.2018)
Solution: Revert Patch v9.0.2018
(Girish Palya)
bug fix: complete_info() gives wrong results
1) complete_info() reverses list of items during <c-p>
2) 'selected' item index is wrong during <c-p>
3) number of items returnd can be wrong
Solution:
- Decouple 'cp_number' from 'selected' index since they need not be
correlated
- Do not iterate the list backwards
- Add targeted tests

Problem: complete_info() skips entries with 'noselect'
Solution: Check, if first entry is at original text state
Unfortunately, Commit daef8c74375141974d61b85199b383017644978c
introduced a regression, that when ':set completeopt+=noselect' is set
and no completion item has been selected yet, it did not fill the
complete_info['items'] list.
This happened, because the current match item did not have the
CP_ORIGINAL_TEXT flag set and then the cp->prev pointer did point to the
original flag item, which caused the following while loop to not being
run but being skipped instead.
So when the 'noselect' is set, only start with to the previous selection
item, if the initial completion item has the CP_ORIGINAL_TEXT flag set,
else use the 2nd previous item instead.

Problem: Completion menu may be wrong
Solution: Check for the original direction of the completion menu,
add more tests, make it work with 'noselect'
completion: move in right direction when filling completion_info()
When moving through the insert completion menu and switching directions,
we need to make sure we start at the correct position in the list and
move correctly forward/backwards through it, so that we do not skip
entries and the selected item points to the correct entry in the list
of completion entries generated by the completion_info() function.
The general case is this:
1) CTRL-X CTRL-N, we will traverse the list starting from
compl_first_match and then go forwards (using the cp->next pointer)
through the list (skipping the very first entry, which has the
CP_ORIGINAL_TEXT flag set (since that is the empty/non-selected entry
2) CTRL-X CTRL-P, we will traverse the list starting from
compl_first_match (which now points to the last entry). The previous
entry will have the CP_ORIGINAL_TEXT flag set, so we need to start
traversing the list from the second prev pointer.
There are in fact 2 special cases after starting the completion menu
with CTRL-X:
3) CTRL-N and then going backwards by pressing CTRL-P again.
compl_first_match will point to the same entry as in step 1 above,
but since compl_dir_foward() has been switched by pressing CTRL-P
to backwards we need to pretend to be in still in case 1 and still
traverse the list in forward direction using the cp_next pointer
4) CTRL-P and then going forwards by pressing CTRL-N again.
compl_first_match will point to the same entry as in step 2 above,
but since compl_dir_foward() has been switched by pressing CTRL-N
to forwards we need to pretend to be in still in case 2 and still
traverse the list in backward direction using the cp_prev pointer
For the 'noselect' case however, this is slightly different again. When
going backwards, we only need to go one cp_prev pointer back. And
resting of the direction works again slightly different. So we need to
take the noselect option into account when deciding in which direction
to iterate through the list of matches.

Problem: completion shows current word after completion restart
Solution: remove the word being completed after completion restart
The word being completed is shown in a completion list after completion
restart, because it isn't removed from the current buffer before
searching for matches.
Also adjust `Test_complete_add_onechar` to match the new behavior.

Problem: complete_info() returns wrong index
Solution: Make order of 'info' in completion_info consistent
Start the iteration from the same point and follow the same direction as
done when assigning the completion numbers. This way we remove the
dependence on the completion direction and make the order of 'info'
consistent.
