} It looks, like this does not work with extended glob patterns (3.1.6 pure or
} pws-1):
}
} bor@itsrm2:~%> print ${(SM)foo#([[:digit:]])#}
This is at least partly consistent:
zagzig<7> foo=ab12xy
zagzig<8> print ${(SM)foo#*}
zagzig<9>
Since a closure can match the empty string, the shortest matched portion
is nothing. However, asking for the longest match definitely doesn't work:
zagzig<9> print ${(SM)foo##*}
ab12xy
zagzig<10> print ${(SM)foo##([[:digit:]])#}
zagzig<11>
} there is subtle problem: searching for "...sub1 ...sub2..." may give
} different results as searching for sub1 first and then for sub2
True.
