Review Comment:
Ah, I see. This is intentional, but is more of a stylistic difference than
anything else. Traditionally, (accidental diversion into typography) a space
after a sentence would use an em space (the same with as a capital M) after a
sentence, wider than the spacing between words. This isn't possible in
monospaced fonts, so typewriters would emulate the em space by using two
spaces. Exactly which is better has since become the topic of a great many
flame wars.
I was curious, and it looks like double-spacing after a sentence is twice as
common as single-spacing in the TVM repo, with the Apache copyright header
being the most prominent example.
```bash
# Count the number of sentences followed by one space
$ find . \
\( -path ./3rdparty -o -path "./build*" \) -prune -o \
\( -name "*.cc" -o -name "*.h" \) \
-exec grep '[A-Za-z]\{2\}\. [A-Za-z]' {} /dev/null \; \
| wc --lines
