+# multicomp() {
+# Completes all manner of files given prefixes for each path segment.
+# e.g. s/z/s -> src/zsh-2.4/src
+#
+# Usage: e.g.
+# compctl -D -f + -U -Q -S '' -K multicomp
+#
+# Note that exactly matched directories are not expanded, e.g.
+# s/zsh-2.4/s<TAB> will not expand to src/zsh-2.4old/src.
+# Will expand glob patterns already in the word, but use complete-word,
+# not TAB (expand-or-complete), or you will get ordinary glob expansion.
+# Requires the -U option to compctl.
+# Menucompletion is highly recommended for ambiguous matches.
+# Liable to screw up escaped metacharacters royally.
+# $fignore is not used: feel free to add your own bit.
