[v.7.8.6 regression] Vertical Edge Settings no longer works with Split Lines (Ctrl-I)

[mhya2020]

Description of the Issue

v.7.8.6 introduced the ability to have multiple Vertical Edges, but it breaks an existing
feature, i.e. Split Lines (Ctrl-I) no longer works with single Vertical Edge.

Steps to Reproduce the Issue

1. Settings/Preferences/Editing/Vertical Edge Settings: enter a single number, e.g. 80, into the text box.
2. Leave "Background mode" unchecked.
3. Enter text with more than 80 characters in a single line
4. press Ctrl-I (Split Lines)

Expected Behavior

The single line is expected to split into multiple lines, where each line is less than 80 characters long.

Actual Behavior

Nothing happened after pressing Ctrl-I.

Workaround: Settings/Preferences/Editing/Vertical Edge Settings: tick the "Background mode" box.

This will bring back the "Split Lines (Ctril-I)" function. Thereafter, you can uncheck "Background mode" box and Split Lines will continue to work.

I have a similar issue.. But doesn't involve "Split Lines" at all:
I used 80 for "Vertical Edge" in past.
When I encountered "You can define Several Column Markers..." I thought great now I can do 132 also for "comments edge"...
At first it seemed to work perfectly.
Later I noticed that the "Vertical Edge" was in the wrong place: 89! (See attached screen capture).
When I tried to reset to old way (Single Column Marker):
a) found previously mentioned extra space after 80 (removing it=no help)
b) cannot put Vertical Edge in correct position, Unless I use 71!
c) out of curiosity, I tried putting back the 132 edge, but as I types 1, 3, 2... I noticed:
i) after I had typed "80 1": the "2nd line" appeared in the correct position (between 1st & 2nd char.)
ii) after I had typed "80 13": the "2nd line" moved to an incorrect position (right in the middle of the 15th char.)
iii) after I had typed "80 132": the "2nd line" moved to an incorrect position (between 147th & 148th char.)

I know, I know, this is a bit off-topic. But this multi-line feature is causing other issues...
As a programmer myself, I always like as much info as possible when talking bugs... Nough said!

Hi,
I just want to add my support to have the prior function of Ctrl-I in 7.8.5 restored as an option -- Split lines at the Vertical Edge, no matter what the width of the window is. I use Notepad++ with wide windows a lot and often split only certain lines at 80 characters.

Thanks,
Ross
