All features of the filter and vim modules work with the latest beta,

The leading spaces are stripped before the buffer is saved to the file
temp.tmp. Is it possible for the leading space NOT to be stripped? (If
not, I'll just document this as a feature :-).

it is actually a feature to align the left edge relative to the least
indented so that we can use them inside other constructs
Now, as you're not afraid of low level code:
\unprotect
\unexpanded\def\StartAditya
{\buff_pickup
{Aditya}%
{StartAditya}%
{StopAditya}%
{}%
{\savebuffer[file=test-temp.tmp,prefix=no,list=Aditya]}%
\zerocount}
This is perfect as I am already using `\grabbufferdata` in my code. I can
easily adapt it to use `\buff_pickup` instead. Thanks!.
Does what you want but of course it's sort of ugly for a module to do that.
What we can do is this which is still ugly but picking up verbatim is
always ugly:
\def\buff_start_indeed#1#2#3#4%
{\edef\p_strip{\namedbufferparameter{#1}\c!strip}%
\normalexpanded{\buff_pickup{#2}{#3}{#4}{}{\buff_stop{#4}}\ifx\p_strip\v!no\zerocount\else\plusone\fi}}
\protect
I want this to be configurable at runtime and the vim module already has code
that enables `strip=yes` and `strip=no` options (I do this via a function in
vim so that it works with both mkii and mkiv; although I don't think that
anyone uses the mkii module any longer).
I added `strip=yes` option to the filter module, which is now the default
option. See "Stripping leading whitespace" in the module documentation
(https://github.com/adityam/filter). This is a MkIV only feature and I
will not implement it in MkII.
I also made `strip=yes` to be the default in t-vim (to be consistent with
t-filter). In t-vim, the `strip` option works with both mkii and mkiv.
