syntax highlighting for all formats supported by "highlight"
The highlight tool can be given any of the supported file extensions
as its -S parameter. This patch replaces the case-switch by extracting
the extension from the supplied file name and passing it to highlight.
However, this requires a shell supporting the ${var##pattern} syntax,
like dash or bash.
Unknown extensions cause a fall-back to plain text using the --force
switch. Error messages are redirected to /dev/null.
A special case maps Makefile and Makefile.* to the "mk" extension.
The total overhead is reduced by calling "exec highlight". No forks are
needed during script execution.
