-Opening delimiters
+.Ss Punctuation and Spacing
+If punctuation is set apart from words, such as in the phrase

+.Pc
+is not preceded by whitespace.
.Pp
-Note that reserved words only register as such as if they appear as
-standalone tokens, either in parsed lines or streams of text. Thus, the
-following fragment:
-.Bd -literal -offset XXXX
-this self is not that of the waking , empirically real man
-.Ed
-.\" PARAGRAPH
+If the input is

+these rules are also applied to macro arguments when appropriate.

-\&...correctly adjusts the comma spacing to
-.Dq this self is not that of the waking , empirically real man .
-However, if the comma were part of
-.Dq ,empirically ,
-it would not.
+White-space, in non-literal (normal) mode, is stripped from input and
+replaced on output by a single space. Thus, if you wish to preserve
+multiple spaces, they must be space-escaped
+.Sq \e\
+or used in a literal display mode, e.g.,
+.Sq \&Bd \-literal
+in
+.Xr mdoc 7 .
.\" SUB-SECTION
.Ss Input Formats
The
.Xr mdoc 7
format is
.Em strongly
-recommended;
+recommended;
.Xr man 7
should only be used for legacy manuals.
.Pp
A third option,
.Fl m Ns Ar andoc ,
-which is also the default, determines encoding on-the-fly. If multiple
-files are passed in, each has its file-type determined this way. If
-multiple files are passed and
+which is also the default, determines encoding on-the-fly: if the first
+non-comment macro is
+.Sq \&Dd
+or
+.Sq \&Dt ,
+the
+.Xr mdoc 7
+parser is used; otherwise, the
+.Xr man 7
+parser is used.
+.Pp
+If multiple
+files are specified with
+.Fl m Ns Ar andoc ,
+each has its file-type determined this way. If multiple files are
+specified and
.Fl m Ns Ar doc
or
.Fl m Ns Ar an
is specified, then this format is used exclusively.

.Ss Output Formats
The
utility accepts the following
.Fl T
arguments:
-.Bl -tag -width XXXXXXXXXXXX -offset XXXX
-.It Ar ascii
+.Bl -tag -width Ds
+.It Fl T Ns Ar ascii
Produce 7-bit ASCII output, backspace-encoded for bold and underline
styles. This is the default.
-.It Ar tree
+.It Fl T Ns Ar tree
Produce an indented parse tree.
-.It Ar lint
+.It Fl T Ns Ar lint
Parse only: produce no output.

+.Pp
+If multiple input files are specified, these will be processed by the

.Ss Compiler Options
Default compiler behaviour may be overriden with the
.Fl f
flag.
-.Bl -tag -width XXXXXXXXXXXXXX -offset XXXX
+.Bl -tag -width Ds
.It Fl f Ns Ar ign-scope
When rewinding the scope of a block macro, forces the compiler to ignore
scope violations. This can seriously mangle the resulting tree.

-Ignore invalid escape sequences.
-.It Fl f Ns Ar ign-macro
-Ignore unknown macros at the start of input lines (default for
-.Xr man 7
-parsing).
+.It Fl f Ns Ar no-ign-escape
+Don't ignore invalid escape sequences.
.It Fl f Ns Ar no-ign-macro
-Do not ignore unknown macros at the start of input lines (default for
-.Xr mdoc 7
