WW-4995 Add trimBody attribute to set tag
> Enhancement for s:set tag to improve tag body whitespace control.

> Project: Struts 2
> Issue Type: Improvement
> Components: Core Tags

> Environment: All environments.
> Reporter: James Chaplin

> 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).
