 The type specifier can be either '--int' or '--bool', which will make
 'git-config' ensure that the variable(s) are of the given type and
 convert the value to the canonical form (simple decimal number for int,
-a "true" or "false" string for bool). If no type specifier is passed,
+a "true" or "false" string for bool).  Type specifiers currently only
+take effect for reading operations.  If no type specifier is passed,
 no checks or transformations are performed on the value.
