comment on FAQ item 4.16 "trim whitespace"

[Andrew Poulos]

White space includes \t\r\n\v\f.

I wrongly took it to mean just spaces " " so when I ran the 'trim'
function it stripped some of my formatting.

Perhaps the FAQ item should either include a definition for white space
or the code be modified to only trim spaces?

This is the normal definition of "white space" throughout the world of
computers.

One should not presume that those who need to read the FAQ are so widely
aware, especially in the presence of a counter-example.

"To trim only ordinary spaces, replace '\s' by '[ ]' or '\x20' or
'\u0020'." could easily be added and would illustrate other points.
