Use
:verbose set iskeyword?
to find out, where it was last modified. I did so and it told me, it was
set by syntax/sh.vim
Looking into the corresponding syntax file, I find this:
,----[ syntax/sh.vim ]-
| " AFAICT "." should be considered part of the iskeyword. Using iskeywords in
| " syntax is dicey, so the following code permits the user to
| " g:sh_isk set to a string : specify iskeyword.
| " g:sh_noisk exists : don't change iskeyword
| " g:sh_noisk does not exist : (default) append "." to iskeyword
| if exists("g:sh_isk") && type(g:sh_isk) == 1 " user specifying iskeyword
| exe "setl isk=".g:sh_isk
| elseif !exists("g:sh_noisk") " optionally prevent
appending '.' to iskeyword
| setl isk+=.
| endif
`----
So simply put into your .vimrc:
:let g:sh_noisk=1
Best,
Christian
