I do not think that *any* fact deserves adding *any* character to the
&iskeyword option. The problem is not that some software thinks that
identifiers may contain certain characters. The problem is that when I
do dw with cursor on x I *expect* it to delete x *everywhere*.

It is absolutely not fun remembering that "fucking sh *syntax* (not
even filetype!) file messes up my keybindings so that `w` now moves
over a dot, fucking erlang syntax file adds dollar and at signs there,
…". Too many information and messing with &iskeyword really makes `w`
(and other based on the word definition) movement not predictable in
any new filetype.

Do not remember where I suggested this, but I think that &iskeyword
value should be saved before sourcing syntax files and then restored
after sourcing. And :syntax should remember effective &iskeyword
value, so that a) syntax files work and b) user settings are
untouched.

And I use ksh, to test that some of my or another person's scripts are
truly portable. But not as a shell.
