3# regular expression test set
4# Lines are at least three fields, separated by one or more tabs.  "" stands
5# for an empty field.  First field is an RE.  Second field is flags.  If
6# C flag given, regcomp() is expected to fail, and the third field is the
7# error name (minus the leading REG_).
8#
9# Otherwise it is expected to succeed, and the third field is the string to
10# try matching it against.  If there is no fourth field, the match is
11# expected to fail.  If there is a fourth field, it is the substring that
12# the RE is expected to match.  If there is a fifth field, it is a comma-
13# separated list of what the subexpressions should match, with - indicating
14# no match for that one.  In both the fourth and fifth fields, a (sub)field
15# starting with @ indicates that the (sub)expression is expected to match
16# a null string followed by the stuff after the @; this provides a way to
17# test where null strings match.  The character `N' in REs and strings
18# is newline, `S' is space, `T' is tab, `Z' is NUL.
19#
20# The full list of flags:
21#	-	placeholder, does nothing
22#	b	RE is a BRE, not an ERE
23#	&	try it as both an ERE and a BRE
24#	C	regcomp() error expected, third field is error name
25#	i	REG_ICASE
26#	m	("mundane") REG_NOSPEC
27#	s	REG_NOSUB (not really testable)
28#	n	REG_NEWLINE
29#	^	REG_NOTBOL
30#	$	REG_NOTEOL
31#	#	REG_STARTEND (see below)
32#	p	REG_PEND
33#
34# For REG_STARTEND, the start/end offsets are those of the substring
35# enclosed in ().
