lib/survex.pot,src/commands.c,tests/cavern.tst,
tests/omitfixaroundsolve.out,tests/omitfixaroundsolve.svx: In the
case of more than one *fix without coordinates, still actually fix
the second and subsequent ones, to avoid then triggering bogus errors
about unconnected surveys.

actual to expected, as the latter is confusing (at least to me).
tests/cavern.tst: Use "cmp -s" in another case to quietly compare
files.
lib/: Update translations.
lib/survex.pot,src/commands.c,tests/cavern.tst,tests/cs.svx,
tests/csbad.out: Issue an error is a station has already been fixed
when *cs is first used.
lib/,src/commands.c: Fix typo in two recently added messages; drop
message which is no longer used.
lib/survex.pot,src/commands.c,tests/csbad.out: If proj fails to
handle a custom cs description, report pj_strerrno().
