Well, I guess this is mostly a matter of taste. Personally, I find it more
readable with one line than 30 per record. Zhakov suggested to switch
to tab characters. I disliked that proposal because a tab might be
confused to a space, but probably not often and never by a computer:-)
But if you for some reason load the file in an editor that munges the
tabs, your bets are off...
We could use spaces and require spaces to be escaped if that improves
readability. (I guess my notion of readability is somewhat different
than others'). I don't have a strong opinion here, but I think it is
useful to use different separators for fields and records. Note that
there is no known count of fields for the sake of extensibility.
NOte that I (hopefully) improved readability by replacing boolean "t"
with field names. Seeing "deleted" says far more than a "t" somewhere
on the line. It increases the size of the file somewhat, but I don't
think that's a probem performancewise.
