# inserted {...} features tests may have changed line numbers and/or ordering

# comments beyond this point are verbatim from the original input

# this file contains a script of tests to run through regress.exe

# comments start with a semicolon and proceed to the end of the line

# changes to regular expression compile flags start with a "-" as the first
# non-whitespace character and consist of a list of the printable names
# of the flags, for example "match_default"
#
# Other lines contain a test to perform using the current flag status
# the first token contains the expression to compile, the second the string
# to match it against. If the second string is "!" then the expression should
# not compile, that is the first string is an invalid regular expression.
# This is then followed by a list of integers that specify what should match,
# each pair represents the starting and ending positions of a subexpression
# starting with the zeroth subexpression (the whole match).
# A value of -1 indicates that the subexpression should not take part in the
# match at all, if the first value is -1 then no part of the expression should
# match the string.
