[MPlayer-dev-eng] [PATCH] Use !isspace() to replace isalnum() in finding subtitle files

[Zuxy Meng]

Hello,

East asian countries represent their language using MBCS, and
characters in that range fail all of iscntrl(c), isblank(c),
isgraph(c), isalnum(c), isprint(c), isspace(c) and ispunct(c), so if
the filename of a video clip contains only such characters, mplayer
will load for it all subtitles under the same directory. The attached
patch fixes it by using negative match instead of the positive one.
