sh: ignore lint error about 'continue' in 'do while' loop

exec.c(575): error: continue in 'do ... while (0)' loop [323]
jobs.c(203): error: continue in 'do ... while (0)' loop [323]

It is certainly a rarely used feature, I saw it the first time today and
had to look up its meaning in the C standard. But after that, I don't
see why a 'continue' statement in a 'do while' loop should be an error.
Maybe a warning since up to now I thought that 'continue' would jump
back to the top of the loop, while it really jumps to the bottom of the
loop body, for all 3 kinds of loops.
