Docs for <SID>

[gi1...@gmail.com]

Hi All,

Looks like the full expansion of the format of expand("<sfile>") changed
sometime between vim 8.1 and 8.2, and as a result it breaks the way some
scripts (LaTeX-Box, in particular) get the SID.

While tracing this down I realized that docs (Vim 8.2) say:

If you need to get the script number to use in a complicated script,
you can use this function:
function s:SID()
return matchstr(expand('<sfile>'), '<SNR>\zs\d\+\ze_SID$')
endfun

Given that expand('<SID>') does the same thing, perhaps you can
replace/remove the above paragraph?

It's not exactly the same thing, and the example can be clearer. I have
changed it to:

func s:ScriptNumber()
return matchstr(expand('<SID>'), '<SNR>\zs\d\+\ze_')
endfunc
