Would you mind testing this patch on HP-UX with CONFIG_SHELL=/bin/sh?
I remember that HP-UX sh is particularly annoying because it gives an
unintelligible error message when the expansion of EXPR in a "case EXPR in"
statement is larger than a certain limit (1024 bytes or so). Maybe
adding a "| head -1" or "| head -2" to the backquoted expression would
be safer?
