Benefits are: drops reference to out-of-line putchar(), fixes a few cases
of failed string merge.

c5fe9f7b72 include sys/resource.h where needed 
We use functions from sys/resource.h in misc applets, but don't include
the header.  This breaks building with newer glibc versions, so add the
include where needed.

7ce209b9d4 shell_builtin_read: set cc[VMIN] to 1; lineedit: don't clear c_cc[VINTR] 
First change fixes "read -n NUM". Apparently poll() won't report
data availability if cc[VMIN] > 1 until there are at least cc[VMIN] bytes.

only form is adjusted (article, space between "GPL" and "v2" and so on).
