> Hello Apache Struts Team.
> The current s:set tag performs an automatic _trim()_ on any body content used (when using the <s:set>something</s:set> style with a body).
> The current behaviour limits white-space control for the text body passed to the s:set tag (and makes assigning a single-or-muliple-character whitespace set - e.g. "  " impossible via the tag body)..
> A proposed improvement is to introduce two optional attributes to the s:set tag which will permit the following:
>  * Allow an override to prevent the trim() from happening (helps to preserve existing whitespace)..
>  * Allow the optional removal of all line-breaks from the tag body content (to allow vertical collapsing of tag body content without impacting anything else).
> There is a PR available with a proposed implementation for the enhancement.  I believe having this additional flexibility will be beneficial for some JSP content generation scenarios.
> Please review and advise if this minor enhancement can be considered for inclusion in 2.5.19 (and then ported forward for 2.6).
