That just enables it, doesn't fix the problems caused.
I believe the pattern that failed was \_[0-9]\?\>.
Somehow the \_[] eats the line break and then \> fails to match.
Discovered using the dnsmasq syntax, especially the DnsmasqIPv4
match. Using syntax files as a wild test for regexp works quite well.
But it does not find everything (and I still have too few files to test
with).
Here are some more patterns that still fail:
Multi-byte problem? Marc Weber
echo matchlist('1', '\%#=1\o{\?Ä\Z')
echo matchlist('1', '\%#=2\o{\?Ä\Z')
Difference in matching this pattern: (Marc Weber)
echo matchlist("t", '\%#=1ú\Z')
echo matchlist("t", '\%#=2ú\Z')
Difference in matching this pattern:
echo matchlist('google', '\%#=1\<go*\|go')
echo matchlist('google', '\%#=2\<go*\|go')
Difference in matching this pattern: (Marc Weber)
echo matchlist("\na", '\%#=1\_F')
echo matchlist("\na", '\%#=0\_F')
echo matchlist("\na", '\%#=2\_F')
