Dear Maintainer,

  I found some formatting and textual defects:

1) Remove a superfluous escape character

/home/bg/git/groff/build/../tmac/an-old.tmac:385: backtrace: macro 'B'
troff: <mupdf.1>:131: warning: escape character ignored before '+'

####

2) Change '-' (\-) to '\(en' (en-dash) for a numeric range.

mupdf.1:122:.B [0-9]m
mupdf.1:125:.B [0-9]t
mupdf.1:212:MuPDF is Copyright 2006-2017 Artifex Software, Inc.

#####

3) Add a comma (or \&) after "e.g." and "i.e.", or use English words
(man-pages(7) [package "manpages"]).

199:file to be reloaded automatically, for use in e.g. build scripts.

#####

4) Wrong distance between sentences or protect the indicator.

a) Separate the sentences and subordinate clauses; each begins on a new
line.  See man-pages(7) [package "manpages"] and "info groff".

Or

b) Adjust space between sentences (two spaces),

c) or protect the indicator by adding "\&" after it.

The "indicator" is an "end-of-sentence character" (.!?).

45:(off) and 8 (best). The default value is 8.
48:Sets the full-page tint using hexadecimal color syntax. The default value
67:A left click on a hyper link follows the link. In presentation mode
74:Pan the page. Panning beyond the bottom or top
78:Select text in an area. On X11, the selected text
87:Pan page up or down. Does not change page
117:Mark current page for snap back. Up to 256 pages can be marked.
199:file to be reloaded automatically, for use in e.g. build scripts.
