I was beginning to think that no one would ever ask..

choose one:
a) three periods take up much more room than the requisite 'em'
..
...
m
… << the genuine article
b) … in the editing font is nearly unreadable, and that would be another ASCII code to remember
c) it's yet another of my lazy shortcuts
d) it's just another affectation
e) all of the above
f) c & d only
g) a & b only
