Обсуждение: some additional (small) problems with pg_combinebackup and tablespaces

Tomas Vondra pointed out to me a couple of mistakes that I made with
regard to pg_combinebackup and tablespaces.

One is that I screwed up the long_options array by specifying
tablespace-mapping as no_argument rather than required_argument. That
doesn't break the tests I just committed because, in the actual string
passed to getopt_long(), I wrote "T:", which means the short form of
the option works; only the long form does not.

The other is that the documentation says that --tablespace-mapping is
applied to the pathnames from the first backup specified on the
command line. It should have said "final" rather than "first".

Here is a very small patch correcting these regrettable errors.

Patch LGTM.

In addition to those, unless I'm reading it wrong the current coding seems to
include a "-P" short option which is missing in the command parsing switch
statement (or in the help output):

    while ((c = getopt_long(argc, argv, "dnNPo:T:",

Should that be removed?

A tiny nit-pick in the same area: while not wrong, it reads a bit odd to have
"don't" and "do not" on lines directly next to each other:

    printf(_("  -n, --dry-run             don't actually do anything\n"));
    printf(_("  -N, --no-sync             do not wait for changes to be written safely to disk\n"));

LGTM, only one small error in the commitmessage: s/Gustaffson/Gustafsson/

Oh no! You're in danger of becoming the second person on this project
whose name I chronically misspell. Fixed (I hope) and committed.
