Yes, PATH_MAX by definition is the maximum length of a file path. But I
still have the feeling it is also involved in setting the $PATH
environment variable. As Glenn did report, there are problems on hydra
when setting $PATH to a string longer than 4096 characters. It doesn't
seem to be related to the shell limit of input lines; Glenn reported
that 'getconf LINE_MAX' returns 2048.
