FRIGN ef23f966c5 Refactor strings(1) loop again 
fixing a little out-of-bounds write.

FRIGN 439bf8a157 Fix small issue in strings(1) loop 
It wouldn't print the len'th character.

FRIGN e5b5497773 Add UTF-8-support to strings(1), add t-flag and refactor code 
Previously, the string-length was limited to BUFSIZ, which is an
obvious deficiency.
Now the buffer only needs to be as long as the user specifies the
minimal string length.
I added UTF-8-support, because that's how POSIX wants it and there
are cases where you need this. It doesn't add ELF-barf compared to
the previous implementation.
The t-flag is also pretty important for POSIX-compliance, so I added
it.
The only trouble previously was the a-flag, but given that POSIX
leaves undefined what the a-flag actually does, we set it as default
and don't care about parsing ELF-headers, which has already
turned out to be a security issue in GNU coreutils[0].

FRIGN eee98ed3a4 Fix coding style 
It was about damn time. Consistency is very important in such a
big codebase.

sin 0c5b7b9155 Stop using EXIT_{SUCCESS,FAILURE} 2014-10-02 23:46:59 +01:00
sin b8edf3b4ee Add weprintf() and replace fprintf(stderr, ...) calls 
There is still some programs left to be updated for this.

Many of these programs would stop on the first file that they
could not open.
