Spurious space in \definestartstop

Dear list,

the title says it all.  Please add \ignorespaces in a place you deem
appropriate.  MWE is below.

Cheers, Henri

I'm confused.  Does that mean there is going to be a fix?

no, why should there be? spaces are never ignored after the last [...] 
that is checked for unless a command has an explicit \ignorespaces

I'm not convinced.  Both "before" and "commands" see a \relax and therefore
\ignorespaces is dropped.  I can put \removeunwantedspaces there but that
deletes the space before \start.  The \framed command correctly drops the space
after the options.

You assume \start[<...>] ... \stop is linked to \definestartstop but 
this isn’t the case,
what the environment does is to generate a start-command with the argument
but this works for every environment, e.g. \start[itemize] ... \stop 
does the same
as \startitemize ... \stopitemize.

Adding the \ignorespace is not an option in this case because it would 
effect
all environments which you use with the argument for \start.

I'm not asking to add \ignorespaces to the definition of \start.  I'm rather
asking, where I have to but \ignorespaces in the setup to eat the space after
the options I pass to \start.

Re: Spurious space in \definestartstop

[Alan Braslau]

Might I add that the use of a command containing spaces in its name is
spurious. Try: \definestartstop[spuriusspacea] \startspuriusspacea ...
\stopspuriuspsacea, and then come up with a better name!

Why do use insinst on the use of \start, when you create a new 
command/environment
with \definestartstop you get additional commands for the instance where 
the space
at the begin of the environment are gobbled.

\definestartstop[Highlight][style=italic,color=red]

\starttext

Text \Highlight{Text} Text

\blank

\input ward\par

\startHighlight
\input ward
\stopHighlight

\input ward

\stoptext

To answer your question where you can add \ignorespace, there is no way 
to add it.
