-Specifies truncation behaviour.
+Specifies truncation behaviour for the remainder of the prompt string.
 The third, deprecated, form is equivalent to `tt(%)var(xstringx)',
 i.e. var(x) may be `tt(<)' or `tt(>)'.
 The numeric argument, which in the third form may appear immediately
 after the `tt([)', specifies the maximum permitted length of
-the various strings that can be displayed in the prompt.  If this
-integer is zero, or missing, truncation is disabled.  Truncation is
-initially disabled.

+place of the truncated portion of any string; note this does not
+undergo prompt expansion.
 
 The forms with `tt(<)' truncate at the left of the string,
 and the forms with `tt(>)' truncate at the right of the string.
 For example, if the current directory is `tt(/home/pike)',
 the prompt `tt(%8<..<%/)' will expand to `tt(..e/pike)'.
 In this string, the terminating character (`tt(<)', `tt(>)' or `tt(])'),
-or in fact any character, may be quoted by a preceding `tt(\)'.
-% escapes are em(not) recognised.
+or in fact any character, may be quoted by a preceding `tt(\)'; note
+when using tt(print -P), however, that this must be doubled as the
+string is also subject to standard tt(print) processing, in addition
+to any backslashes removed by a double quoted string:  the worst case
+is therefore `tt(print -P "%<\\\\<<...")'.
+
 If the var(string) is longer than the specified truncation length,
 it will appear in full, completely replacing the truncated string.
+
+The part of the prompt string to be truncated runs to the end of the
+string, or to the end of the next enclosing group of the `tt(%LPAR())'
+construct, or to the next truncation encountered at the same grouping
+level (i.e. truncations inside a `tt(%LPAR())' are separate), which
+ever comes first.  In particular, a truncation with argument zero
+(e.g. `tt(%<<)') marks the end of the range of the string to be
+truncated while turning off truncation from there on. For example, the
+prompt '%10<...<%~%<<%# ' will print a truncated representation of the
+current directory, followed by a `tt(%)' or `tt(#)', followed by a
+space.  Without the `tt(%<<)', those two characters would be included
+in the string to be truncated.
