You can reduce the above to this:

proc p.wc {content} {
return [llength [regsub -all -inline {\S+} $content]]
}

And save having to create a trimmed version of content, save creating a
second copy of content with runs of whitespace converted to a single
space, and save having to then scan and split content on those spaces.
