Run emacs -Q /tmp/configure.ac, paste in the following lines:

AC_DEFUN([FOO_DEP],
dnl AC_ARG_WITH([lang$1],
dnl   [
dnl     AS_HELP_STRING([--with-lang$1],
dnl     [Source directory for $2, otherwise uses installed files])
dnl   ],
dnl   [
dnl     SRC$1=$withval
dnl     echo "Using $2 from $SRC$1"
dnl   ],
dnl   [ 
dnl     PKG_CHECK_MODULES([$2], [$2])
dnl     SRC1=`pkg-config --variable=srcdir $2`
dnl   ])
)

then mark the dnl-ed lines, and do M-x uncomment-region. 

Expected result:

AC_DEFUN([FOO_DEP],
AC_ARG_WITH([lang$1],
  [
    AS_HELP_STRING([--with-lang$1],
    [Source directory for $2, otherwise uses installed files])
  ],
  [
    SRC$1=$withval
    echo "Using $2 from $SRC$1"
  ],
  [ 
    PKG_CHECK_MODULES([$2], [$2])
    SRC1=`pkg-config --variable=srcdir $2`
  ])
)

Actual result:

AC_DEFUN([FOO_DEP],
dnl AC_ARG_WITH([lang$1],
  [
dnl     AS_HELP_STRING([--with-lang$1],
    [Source directory for $2, otherwise uses installed files])
dnl   ],
  [
dnl     SRC$1=$withval
    echo "Using $2 from $SRC$1"
dnl   ],
  [ 
dnl     PKG_CHECK_MODULES([$2], [$2])
    SRC1=`pkg-config --variable=srcdir $2`
dnl   ])
)
