Package: grep
Version: 2.5.1.ds2-4
Severity: normal
Tags: upstream

Isn't .* supposed to match 0 or more of any char?
$ qp-encode < n
one=E2=80=99s neck
$ env - grep -c one.*neck n
1
$ env - LC_CTYPE=zh_TW.Big5 grep -c one.*neck n
0 #WHY?
$ env - grep -c one.....neck n
1
$ env - LC_CTYPE=zh_TW.Big5 grep -c one.....neck n
0 #WHY?
$ env - LC_CTYPE=zh_TW.Big5 grep -c one....neck n
0
$ env - LC_CTYPE=zh_TW.Big5 grep -c one...neck n

$ env - LC_CTYPE=zh_TW.Big5 grep -c one..neck n
