vi: fix FEATURE_VI_REGEX_SEARCH to respect LIMITED (one-line) search
If busybox is compiled with FEATURE_VI_REGEX_SEARCH enabled, command
":s/x/y/" searches not only in the current line, but continues search
after it. This makes range searches (":1,3s/x/y/") work incorrect. For
example file "./test":
1
2
3
$ vi ./test
:1,2s/3/e/
gives us:
1
2
e
function old new delta
char_search 213 241 +28
