Why doesn't ls use fnmatch() when matching against extensions in $LS_COLORS?

The test that ls employs for determining if a file should be given some certain
kind of highlighting when listed currently uses strncmp() to compare the last
few characters of a file's name against the extensions found in $LS_COLORS.

Why is fnmatch() not being used to do this test?  As it is now, the '*' can only
be given as a prefix and is just part of a big charade.

It also makes matching things like *.r[0-9][0-9] for parts in a rar-archive set
impossible without listing them explicitly in your dircolors file.

I assume that there is some higher reason for this, as a patch to use fnmatch()
instead of strncmp() is incredibly trivial, but I fail to see what it is.

Thanks.
