octave-kai/gnulib-hg: lib/argmatch.c annotate

annotate lib/argmatch.c @ 10256:af15fcca9925

getdate.y: do not ignore TZ with relative day, month or year offset * lib/getdate.y (get_date): Move the tz-handling block to follow the relative-date-handling, since otherwise, the latter would clobber the sole output (an updated Start value) of the tz-handling block. * tests/test-getdate.c: Tests for the fix
