In version 7.00.1352409000 20121108 and later, the
and code combinations %l/ and %l: - which print REX
expressions to match directory separators and search path separators
respectively - have slightly different output. The expressions are
always full character classes (i.e. bracketed), and do not have a
repetition operator ("=") appended. This allows the
repetition operator to be changed more easily by the user, by simply
appending it when printing.
