Coming from SunOS 4 times I agree. That "X$var" comparing with "Xvalue" idiom is or at least was very common in system shell scripts. No need to document, that is just practical shell language programming knowledge. The same to not using "-n" or "-z" for platform independent shell script. It seems to me that POSIX and the later Unix standards still do not standardize the allowed shell expression syntax. There is a standard "test" commandline util, but IMHO that's not the same.
