for arg do loop

See http://gnu.ist.utl.pt/software/autoconf/manual/autoconf-2.57/html_chapter/autoconf_10.html

To loop over positional arguments, use:

for arg
do
  printf %s\\n "$arg"
done

DANGER: You must not leave the do on the same line as for, such as in the example caode below. This is because some shells improperly grok it.

# DANGER
for arg; do
  printf %s\\n "$arg"
done

DANGER: If you want to explicitly refer to the positional arguments, given the $@ bug, then you can use the example code below. But keep in mind that Zsh, even in Bourne shell emulation mode, performs word splitting on ${1+"$@"}; see Shell Substitutions, item `$@', for more.

# DANGER
for arg in ${1+"$@"}; do
  printf %s\\n "$arg"
done
