tag (say to preserve original whitespace) results in double-spaced lines, taking up too much vertical space. Using the
tag prevents this, but whitespace is not preserved. Adding appears to be a (n ugly and hard to edit) work-around, but while leading non-breaking spaces within
tags are retained in previews, they are stripped in the posted comment.
As a number of askMefi's ask for program code, and as even some FPPs may contain code fragments, this makes the code unreadable or even syntactically incorrect in languages than foolishly assign meaning to whitespace.
And it's a pure pain to spend the time to carefully add the whitespace and to Google the correct HTML entities for a post, only to see them stripped out.
