Bug in execvp/execlp

[pdac at qtlon.UUCP]

 According to the "man" entry, these 2 routines should duplicate the shell's
action in searching for an executable file using the PATH variable. However,
it seems that as well as splitting the pathlist on ':', it also splits on '-'.
This seems to be deliberate from the source code, but neither the boure shell
nor "csh" does it!

 I've tried this out on both 4.1bsd and 4.2bsd and they both have the same
problem.
