+ If a list is sorted according to this function and if you want to

+
+ Whitespace example:
+
+ Say your partial symtab contains: "foo<char *>", "goo". Then, if
+ we try to do a search for "foo<char*>", strcmp will locate this
+ after "foo<char *>" and before "goo". Then lookup_partial_symbol
+ will start looking at strings beginning with "goo", and will never
+ see the correct match of "foo<char *>".
+
+ Parenthesis example:
+
+ In practice, this is less like to be an issue, but I'll give it a
+ shot. Let's assume that '$' is a legitimate character to occur in
+ symbols. (Which may well even be the case on some systems.) Then
+ say that the partial symbol table contains "foo$" and "foo(int)".
+ strcmp will put them in this order, since '$' < '('. Now, if the
+ user searches for "foo", then strcmp will sort "foo" before "foo$".
+ Then lookup_partial_symbol will notice that strcmp_iw("foo$",
+ "foo") is false, so it won't proceed to the actual match of
+ "foo(int)" with "foo". */
