Thus the behaviour of apropos() can depend on what objects
are in the workspace, which is surely not intended!

There are some weird consequences:
apropos(b) generates an error, while apropos(c) finds a
huge number of partial matches.

The problem is with the first line of the function, i.e.,
    if (!is.character(what)) 
        what <- as.character(substitute(what))

I suggest replacing this with:
    if (!is.character(substitute(what))) 
        what <- as.character(substitute(what))

apropos("sor") works fine.

I have checked this also on Darwin/X11, version 1.6.1
