Now imap-send learned to talk to the server using cURL library,
allow the same GIT_CURL_VERBOSE environment variable to control the
verbosity of the chattering.

Fix recent breakage in Git 2.2 that started creating info/refs and

umask.

is already defined.

Earlier we made "rev-list --object-edge" more aggressively list the
objects at the edge commits, in order to reduce number of objects
fetched into a shallow repository, but the change affected cases
other than "fetching into a shallow repository" and made it
unusably slow (e.g. fetching into a normal repository should not
have to suffer the overhead from extra processing).  Limit it to a
more specific case by introducing --objects-edge-aggressive, a new
option to rev-list.

* bc/fetch-thin-less-aggressive-in-normal-repository:

Traditionally we tried to avoid interpreting date strings given by
the user as future dates, e.g. GIT_COMMITTER_DATE=2014-12-10 when
used early November 2014 was taken as "October 12, 2014" because it
is likely that a date in the future, December 10, is a mistake.

Loosen this and do not tiebreak by future-ness of the date when

(1) ISO-like format is used, and
(2) the string can make sense interpreted as both y-m-d and y-d-m.

* jk/approxidate-avoid-y-d-m-over-future-dates:
  approxidate: allow ISO-like dates far in the future
