Thanks VERY much for implementing this. I too hope it can be incorporated
into the next Vim release. I'll be testing on linux, but can't help with
testing on other platforms.
Meanwhile.... here's a function/command that makes use of this to
automatically figure out "good" tabstops. I don't write vim script very
often, so there may be a more efficient way to do this, but it works.
function! AutoVariableTabstop(...)
let extra = 0
if a:0 > 0
let extra = a:1
endif
let i = 1
let tabs = []
while i <= line("$")
let fields = split(getline(i),"\t",1)
let i = i + 1
let f = 0
while f < len(fields)
let l = strlen(fields[f])+1+extra
if (len(tabs) <= f)
call add(tabs,l)
else
if (l > tabs[f])
let tabs[f] = l
endif
endif
let f = f + 1
endwhile
endwhile
execute "set vts=" . join(tabs,",")
endfunction
command! -nargs=? AutoTabs call AutoVariableTabstop(<args>)
