When input is not a multiple of three bytes in size, pad null
characters instead of garbage. This makes output reproducible.

Taken from FreeBSD:
https://svnweb.freebsd.org/base?view=revision&revision=84715

Even though this is not demanded by POSIX, uuencode(1) in
FreeBSD, OpenBSD, macOS, and GNU, behaves that way.

Clarify the usage message. For PR 49177.

branches: 1.15.20;
Use __dead

Clarify man page with respect to input and output files, and sync usage
message. Prompted by PR 40063 about the usage message.

branches: 1.13.4;
Remove the \n and tabs from the __COPYRIGHT() strings.
Tweak to use a consistent format.

PR/33319: Seebs: base64 is annoying

Thanks to Matt Fleming for implementing a -m switch (base64 mode) for
both uuencode(1) and uudecode(1)! Man-pages updated as well.

Add setprogname call.

de-__P(), ansify, use {g,s}etprogname.

Move UCB-licensed code from 4-clause to 3-clause licence.

Patches provided by Joel Baker in PR 22365, verified by myself.

WARNSify, fix .Nm usage, deprecate register, use err.h

fix typo

Merged with 4.4lite.
Changed to conform to NetBSD's new RCS Id convention.

Well behaved POSIX.2 utilities always call setlocale() and getopt().

#include <unistd.h>, so getopt(), optarg, opterr, optind, and optopt
declarations can be removed from <stdlib.h>.

Minor tweaks: including header files to bring prototypes into scope,
explicitly declaring function return values, etc. to make gcc -Wall
shut up.

Add RCS identifiers.
