+# regular expression test set
+# Lines are at least three fields, separated by one or more tabs. "" stands
+# for an empty field. First field is an RE. Second field is flags. If
+# C flag given, regcomp() is expected to fail, and the third field is the
+# error name (minus the leading REG_).
+#
+# Otherwise it is expected to succeed, and the third field is the string to
+# try matching it against. If there is no fourth field, the match is
+# expected to fail. If there is a fourth field, it is the substring that
+# the RE is expected to match. If there is a fifth field, it is a comma-
+# separated list of what the subexpressions should match, with - indicating
+# no match for that one. In both the fourth and fifth fields, a (sub)field
+# starting with @ indicates that the (sub)expression is expected to match
+# a null string followed by the stuff after the @; this provides a way to
+# test where null strings match. The character `N' in REs and strings
+# is newline, `S' is space, `T' is tab, `Z' is NUL.
+#
+# The full list of flags:
+# - placeholder, does nothing
+# b RE is a BRE, not an ERE
+# & try it as both an ERE and a BRE
+# C regcomp() error expected, third field is error name
+# i REG_ICASE
+# m ("mundane") REG_NOSPEC
