minirst: convert ``foo`` into "foo" upon display
This lets us markup many more occurances of inline literals since they
no longer look strange in the terminal output.
Some commands allow the user to specify a date, e.g.:
- backout, commit, import, tag: Specify the commit date.
- log, revert, update: Select revision(s) by date.
Many date formats are valid. Here are some examples::
"Wed Dec 6 13:18:29 2006" (local timezone assumed)
"Dec 6 13:18 -0600" (year assumed, time offset provided)
"Dec 6 13:18 UTC" (UTC and GMT are aliases for +0000)
"Dec 6" (midnight)
"13:18" (today assumed)
"3:39" (3:39AM assumed)
"3:39pm" (15:39)
"2006-12-06 13:18:29" (ISO 8601 format)
"2006-12-6 13:18"
"2006-12-6"
"12-6"
"12/6"
"12/6/6" (Dec 6 2006)
Lastly, there is Mercurial's internal format::
"1165432709 0" (Wed Dec 6 13:18:29 2006 UTC)
This is the internal representation format for dates. unixtime is the
number of seconds since the epoch (1970-01-01 00:00 UTC). offset is
the offset of the local timezone, in seconds west of UTC (negative if
the timezone is east of UTC).
The log command also accepts date ranges::
"<{datetime}" - at or before a given date/time
">{datetime}" - on or after a given date/time
"{datetime} to {datetime}" - a date range, inclusive
"-{days}" - within a given number of days of today
