And back to the two-space after a period issue, there was an excellent
debunking of the myth that two spaces are 'wrong."
And yes, I was an amateur typesetter in high school (yes, real lead type)
and I've written justification algorithms (in 8080 assembly!) for early
proportionally spaced printers.
Short version; original typesetting practice was an "em-space" after a
period -- a space roughly the width of an "m". Standard spacing between
words was usually an "en-space", a space roughly the width of an n. An
em-space is typically twice the width of an en-space.
Typewriters used two spaces after a period to mimic the em/en spacing rule.
Starting in the 20th century, especially in periodicals, the extra space
has been trimmed. By the mid-20th, house style had largely eliminated the
extra spacing after periods.
