*roff systems will interpret the period in the unpatched page as
sentence-ending punctuation and put inter-sentence spacing after it.
(This might not be visible on nroff/terminal devices, but it is more
likely to be on typesetter/PostScript/PDF output).
groff_man(7) in groff 1.22.4 attempts to throw man page writers a bone
here:
\& Zero‐width space. Append to an input line to prevent an end‐of‐
sentence punctuation sequence from being recognized as such, or
insert at the beginning of an input line to prevent a dot or
apostrophe from being interpreted as the beginning of a roff
request.
