This adds support for date expressions such as +12h to
org-matcher-time. The regexp this function uses to parse such relative
expressions already includes the "h" character but doesn't actually
handle that case.

AFAICT org-mode commit ec921a2a68 ("Support hourly repeat cookies")
neglected to add support here.

 Furthermore you can specify a relative date by giving, as the /first/
-thing in the input: a plus/minus sign, a number and a letter---=d=,
-=w=, =m= or =y=---to indicate change in days, weeks, months, or
-years.  With a single plus or minus, the date is always relative to
-today.  With a double plus or minus, it is relative to the default
-date.  If instead of a single letter, you use the abbreviation of day
