[vim/vim] listchars: leadmultispace does not count spaces hidden by scrolling off to the side (Issue #13145)
osthomas
Steps to reproduce
Example:
set listchars=leadmultispace:x--- | hi SpecialKey cterm=NONE gui=NONE guifg=red ctermfg=1
012345678
A
With the full line in view, this renders as:
012345678
x---x---A
Sidescrolling past the first column, this renders as:
12345678
x---x--A
left starting at column 2, right starting at column 1
Expected behaviour
I expected leadmultispace to count the spaces off-screen, rendering as:
12345678
---x---A
Version of Vim

Hm. The *lcs-leadmultispace* documentation is not very explicit. I suppose that the easiest solution would be to decide that «t'ain't a bug, it's a feature» and document in the help (maybe also under *lcs-multispace*) that the first character of the value applies to the first visible space of several.
If, OTOH, Christian prefers to treat it like an actual bug, or if you are savvy enough to delve into the code and fix it, then it would mean a patch somewhere in the C code rather than merely in the options.txt helpfile. But in that case, of course, beware of the risk of introducing another bug somewhere else.
