Subject: [PATCH] Format fixes and other updates in 2020/ferguson2
With this commit I should be able to return to the other entries though
as Landon pointed out I might never finish this and this is a reason it
might not have been as thorough as I could have been (another part is
it's long). Nevertheless the formatting should now be okay along the
lines of what was requested for all the winning entry markdown files.

.SH NAME
recode \- A configuration tool for the IOCCC 2020 Enigma simulator w/various additional features for enhanced usage
.SH SYNOPSIS
-\fBrecode [options]\fP
+\fBrecode\fP [\fB\-v\fP] [\fB\-r\fP] [\fB\-f\fI\fP\fP] [\fB\-R\fI\fP\fP] [\fB\-l\fI\fP\fP]
.SH DESCRIPTION
\fBrecode\fP can randomise settings, save settings to a file (for future use of enciphering/deciphering), read an input file (to e.g. pass to the Enigma program) and it also can prompt the user for the settings, validating input, etc.
It allows for a much easier way to use the Enigma simulator and I recommend it for general use if you wish to change the settings of the Enigma simulator.
.SH OPTIONS

\fB\-i\\fP
Alias for \fI\-f\fP option.
-.PP
+.TQ
\fB\-R\\fP
Parse settings string (or file with the same format). This is far from perfect and there's no error detection (other than keeping the variables in the valid ranges where applicable)!
Notice that there is no space after the \fB\-R\fP.
