</div>AFAIK, all the modules which currently use "*" do so because it's part<br>
of standard glob or regex syntax.<br>

For most utilities, using the shell's wildcard syntax makes the need<br>
for quoting inevitable (e.g. the find(1) manual page explicitly<br>
mentions this in relation to the -name, -iname etc options).<br>
<br>
GRASS "gets away with it" because of the option=value syntax and the<br>
fact that "=" is uncommon in filenames.<br>

</div>I doubt that we'd change it in the sense of abandoning support for the<br>
existing syntax, but modifying G_parser() to allow either form<br>
probably wouldn't require much work.<br>
