Wait a second.... is the model a typewritten page or a published
page? Typists follow the rule of adding an extra space between
sentences within a paragraph. The rule for books (and by extension,
anything that does not use a fixed-pitch, monospaced font) is to use
the same space between sentences as between words. (I checked the
standard references, both "Words into Type" and the "Chicago Manual
of Style," on this.)
> in Tex you have to escape a period after an abbreviation
I'm not a Tex user, so I don't know why Tex adds the extra space. But
it seems to me that there should be no issue here.
A WWW document (which uses proportional fonts) should have the same
space between sentences as between words.
Besides, it's easier that way.
