+# Match words by the style given below.  The matching depends on the
+# cursor position.  The matched_words array is set to the matched portions
+# separately.  These look like:
+#    <stuff-at-start> <word-before-cursor> <whitespace-before-cursor>
+#    <whitespace-after-cursor> <word-after-cursor> <whitespace-after-word>
+#    <stuff-at-end>
+# where the cursor position is always after the third item and `after'
+# is to be interpreted as `after or on'.  Some
+# of the array elements will be empty; this depends on the style.
+# For example
+#    foo bar  rod stick
+#            ^
+# with the cursor where indicated whill with typical settings produce the
+# elements `foo ', `bar', ` ', ` ', `rod', ` ' and `stick'.
+#
+# The style word-style can be set to indicate what a word is.
+# The three possibilities are:
+#
+#  shell	Words are shell words, i.e. elements of a command line.
+#  whitespace	Words are space delimited words; only space or tab characters
+#               are considered to terminated a word.
+#  normal       (the default): the usual zle logic is applied, with all
+#		alphanumeric characters plus any characters in $WORDCHARS
+#		considered parts of a word.  The style word-chars overrides
+#		the parameter.  (Any currently undefined value will be
+#		treated as `normal', but this should not be relied upon.)
+#  specified    Similar to normal, except that only the words given
+#               in the string (and not also alphanumeric characters)
+#               are to be considerd parts of words.
+#  unspecified  The negation of `specified': the characters given
+#               are those that aren't to be considered parts of a word.
+#               They should probably include white space.
+#
+# In the case of the `normal' or `(un)specified', more control on the
+# behaviour can be obtained by setting the style `word-chars' for the
+# current context.  The value is used to override $WORDCHARS locally.
+# Hence,
+#   zstyle ':zle:transpose-words*' word-style normal
+#   zstyle ':zle:transpose-words*' word-chars ''
+# will force bash-style word recognition, i.e only alphanumeric characters
+# are considerd parts of a word.  It is up to the function which calls
+# match-words-by-style to set the context in the variable curcontext,
+# else a default context will be used (not recommended).
+#
+# You can override the use of word-chars with the style word-class.
+# This specifies the same information, but as a character class.
+# The surrounding square brackets shouldn't be given, but anything
+# which can appear inside is allowed.  For example,
+#   zstyle ':zle:*' word-class '-:[:alnum:]'
+# is valid.  Note the usual care with `]' , `^' and `-' must be taken if
+# they need to appear as individual characters rather than for grouping.
+#
+# The final style is `skip-chars'.  This is an integer; that many
+# characters counting the one under the cursor will be treated as
+# whitespace regardless and added to the front of the fourth element of
+# matched_words.  The default is zero, i.e. the character under the cursor
+# will appear in <whitespace-after-cursor> if it is whitespace, else in
+# <word-after-cursor>.  This style is mostly useful for forcing
+# transposition to ignore the current character.
