I like this suggestion a lot (if only because it means I don't
have to reformat my existing pages), but then the question
becomes "How many leading spaces?"
I think eight spaces as a minimum is probably too many. Four would work
nicely (and would solve the problem for most of PmWiki's built-in pages),
but I think there are some instances where cut-and-paste may end up with
four leading spaces at the front.
So, I don't know what number of leading spaces would be an appropriate
default. I'd lean to four, but I don't know that setting it at four
will significantly reduce the scope of the problem. (And it may be
that a compromise is ultimately more confusing than either extreme.)
Still, it can always be done as a configuration variable, so that
setting $EnableWSPre to a number such as 1, 4, or 8 results in requiring
that number of leading spaces to treat lines as preformatted text.
What's the consensus opinion here? If we changed PmWiki's default
leading whitespace rule to require four leading spaces instead of one,
would that (a) resolve a lot of the confusion for authors, and
(b) significantly reduce the amount of conversion and updating that
needed to be done to existing pages?
