68b26ff854 Allow passing extended formats
Extended formats can be specified by adding custom format strings to the
end of a long format specifier, separated by a colon (":"). This feature
is currently unused. Extended format support for several format
specifiers will be added in following patches.

2c9499bf27 Use strcmp() instead of strncmp()
strncmp() isn't intended to be a secure strcmp() replacement, it is
designed to be used if you want to compare the first n characters of two
strings. Since we always compare character pointers with string
literals, switch to using strcmp() everywhere.

136e5bc4f7 Fix POSIX compliance
* "WAIT_MYPGRP" isn't POSIX'ish. Relying on this caused compilation
  issues in certain environments (e.g. under Cygwin). As a workaround,
  define "WAIT_MYPGRP" explicitly if it's undefined.

* "P_tmpdir" is an XSI extension. Don't try use it if it isn't
  available.

f77f4647d1 print_*(): Add format specifier to print notes
* Move print_notefile() from "src/args.c" to "src/utils.c".

* Add a "%N" format specifier to print_*(). This invokes
  print_notefile() and prints the content of an item's note file.

  everywhere.

7cc6305588 Do not cast unused return values to void
A small style fix that removes all remaining "(void)" casts. Using these
isn't encouraged in GNU coding guidelines and doesn't serve a certain
purpose, except for satisfying a few static code analysis tools. We
already nuked some of these in previous patches, but this semantic patch
should fix what's left:

    @@

44bc9605d6 Avoid use of printf()/fprintf()
Use one of the following functions where appropriate:

* puts() (whenever we print hard coded strings to stdout)
* fputs() (whenever we print hard coded strings to a stream)
* putchar() (whenever we print a single character to stdout)
* fputc() (whenever we print a single character to a stream)
* strncpy() (whenever we copy hard coded strings to a buffer)

This removes the overhead introduced by the format string parser and
reduces the number of false positive C-format strings spotted by
xgettext(1)'s heuristics.
