+=item pv_escape
+X<pv_escape>
+
+ |const STRLEN count|const STRLEN max
+ |STRLEN const *escaped, const U32 flags
+
+Escapes at most the first "count" chars of pv and puts the results into
+dsv such that the size of the escaped string will not exceed "max" chars
+and will not contain any incomplete escape sequences.
+
+If flags contains PERL_PV_ESCAPE_QUOTE then any double quotes in the string
+will also be escaped.
+
+Normally the SV will be cleared before the escaped string is prepared,
+but when PERL_PV_ESCAPE_NOCLEAR is set this will not occur.
+
+If PERL_PV_ESCAPE_UNI is set then the input string is treated as unicode,
+if PERL_PV_ESCAPE_UNI_DETECT is set then the input string is scanned
+using C<is_utf8_string()> to determine if it is unicode.
+
+If PERL_PV_ESCAPE_ALL is set then all input chars will be output
+using C<\x01F1> style escapes, otherwise only chars above 255 will be
+escaped using this style, other non printable chars will use octal or
+common escaped patterns like C<\n>. If PERL_PV_ESCAPE_NOBACKSLASH
+then all chars below 255 will be treated as printable and
+will be output as literals.
+
+If PERL_PV_ESCAPE_FIRSTCHAR is set then only the first char of the
+string will be escaped, regardles of max. If the string is utf8 and
+the chars value is >255 then it will be returned as a plain hex
+sequence. Thus the output will either be a single char,
+an octal escape sequence, a special escape like C<\n> or a 3 or
+more digit hex value.
+
+If PERL_PV_ESCAPE_RE is set then the escape char used will be a '%' and
+not a '\\'. This is because regexes very often contain backslashed
+sequences, whereas '%' is not a particularly common character in patterns.
+
+Returns a pointer to the escaped text as held by dsv.

+NOTE: the perl_ form of this function is deprecated.

+
+ |const STRLEN count|const STRLEN max\
+ |const char const *start_color| const char const *end_color\
+ |const U32 flags
+
+Converts a string into something presentable, handling escaping via
+pv_escape() and supporting quoting and elipses.
+
+If the PERL_PV_PRETTY_QUOTE flag is set then the result will be
+double quoted with any double quotes in the string escaped. Otherwise
+if the PERL_PV_PRETTY_LTGT flag is set then the result be wrapped in
+angle brackets.
+
+If the PERL_PV_PRETTY_ELIPSES flag is set and not all characters in
+string were output then an elipses C<...> will be appended to the
+string. Note that this happens AFTER it has been quoted.
+
+If start_color is non-null then it will be inserted after the opening
+quote (if there is one) but before the escaped text. If end_color
+is non-null then it will be inserted after the escaped text but before
+any quotes or elipses.

+Returns a pointer to the prettified text as held by dsv.
