This commit slightly improves the formatting of the manuals.  My
OpenBSD machine uses mandoc(1) to format manuals.  I check the manuals
with `mandoc -T lint` and fix most of the warnings.  I also make
other changes where mandoc didn't warn me.
roff(7) says, "Each sentence should terminate at the end of an input
line," but we often forgot this rule.  I insert some newlines after
sentences that had ended mid-line.
roff(7) also says that blank lines "are only permitted within literal
contexts."  I delete blank lines.  This removes some extra blank lines
from mandoc's output.  If I do want a blank line in the output, I call
".sp 1" to make it in man(7).  If I want a blank line in the source,
but not the output, I put a plain dot "." so roff ignores it.
Hyphens used for command-line options, like \-a, should be escaped by
a backslash.  I insert a few missing backslashes.
mandoc warns if the date in .TH doesn't look like a date.  Our manuals
had a missing date or the RCS keyword "$Revision$".  Git doesn't
expand RCS keywords.  I put in today's date, 2017-01-18.
Some manuals used tab characters in filled mode.  That doesn't work.
I use .nf to turn off filled mode, or I use .IP in man(7) to make the
indentation without a tab character.
ack(1) defined a macro .SB but never used it, so I delete the
definition.  I also remove a call to the missing macro .RF.
mandoc warns about empty paragraphs.  I deleted them.  mandoc also
warned about these macro pairs in anm(1):
    .SM
    .B text
The .SM did nothing because the .B text is on a different line.  I
changed each pair to .SB for small bold text.
I make a few other small changes.

| .ad
 | |
| .SH NAME
 | |
| em_decode, em_encode \- compact to readable EM and v.v.
 | |
| .SH SYNOPSIS
 | |
| .B ~em/lib.bin/em_decode
 | |
| [ inputfile [ outputfile ] ]
 | |
| .br
 | |
| .B ~em/lib.bin/em_encode
 | |
| [ inputfile [ outputfile ] ]
 | |
| .SH DESCRIPTION
 | |
| Most programs involved with the EM project only produce and accept
 | |
| EM programs in compact form.
 | |
| These files are only machine readable.
 | |
| A description of this compact form can be found in [1].
 | |
| To inspect the code produced by compilers or to patch them for one reason
 | |
| or another, human readable assembly code is needed.
 | |
| Em_decode produces human readable assembly code from the compact form.
 | |
| .PP
 | |
| Em_decode accepts the normal compact form in both optimized and
 | |
| unoptimized form.
 | |
| .PP
 | |
| Em_encode produces the compact form
 | |
| out of these human readable assembly code.
 | |
| .PP
 | |
| The first argument is the input file.
 | |
| The second argument is the output file.
 | |
| Both programs can act as a filter.
