Feature Request: \startitemize[text]

Feature Request: \startitemize[text]

[Aditya Mahajan]

Hi Hans,

I have always found the space at the beginning of each item in 
\startitemize[text] to be too large. Currently, this is hard coded to be
\emwidth plus \intertwordstretch minus \interwordshrink (line 1132 of 
core-itm.tex with the comment "new per 2006/10/20"). I always end of 
copying the definition of complexdoitemgroupitem to my private modules and 
changing the emwidth in the definition to 0.5\emwidth. Can you please keep 
this key to be configurable with a key (textinbetween)?

BTW, any particular reason not to simply say 
\removeunwantedspaces\space\ignorespaces instead of
\removeunwantedspaces\hskip\emwidth\!!plus\interwordstretch\!!minus\interwordshrink\relax 
\stopitemgroup uses just the first variant.

Thanks,
Aditya

Hi Aditya,

what do you about the following solution, the space between each
item is configurable with the "space" key, the fourth parameter
\dostartitemgroup gobbles we get from \startitemize if we use two
parameters.

Thank you for looking into this old request. This does exactly what I 
want. I just have one comment regarding the default. Maybe, for 
consistency, the space key should behave as in \setupinterlinespace

space=none|small|medium|big|dimension

Other than this, it is perfect. Thanks a lot.

Hans, can this be included in the core?

Thanks,
Aditya

later, i'd rather not touch code now while i'm in the middle some major

so, fro the moment, just collect extension code
