an optional parameter.

Merge branch 'jc/ref-excludes' into jch

People often wished a way to tell "git log --branches" (and "git
log --remotes --not --branches") to exclude some local branches
from the expansion of "--branches" (similarly for "--tags", "--all"
and "--glob=<pattern>").  Now they have one.

* jc/ref-excludes:
  rev-parse: introduce --exclude=<glob> to tame wildcards
  rev-list --exclude: export add/clear-ref-exclusion and ref-excluded API
  rev-list --exclude: tests
  document --exclude option

  builtin/remote: remove postfixcmp() and use suffixcmp() instead
Merge branch 'th/reflog-annotated-tag' into jch

"git log -g $annotated_tag", when there is no reflog history, should
have produced a single output entry (i.e. the ref creation event),
but instead showed the history leading to the tag.

Broken at the design level.  Any reflog entry that points at a non
commit needs to be handled with new code that does not exist yet,
and lifting the "this code handles only commits" without adding
such code does not solve anything.

* th/reflog-annotated-tag:
  reflog: handle lightweight and annotated tags equally
Merge branch 'mh/fetch-tags-in-addition-to-normal-refs' into jch

The "--tags" option to "git fetch" used to be literally a synonym to
a "refs/tags/*:refs/tags/*" refspec, which meant that (1) as an
explicit refspec given from the command line, it silenced the lazy
"git fetch" default that is configured, and (2) also as an explicit
refspec given from the command line, it interacted with "--prune"
to remove any tag that the remote we are fetching from does not
have.

This demotes it to an option; with it, we fetch all tags in
addition to what would be fetched without the option, and it does
not interact with the decision "--prune" makes to see what
remote-tracking refs the local has are missing the remote
counterpart.

* mh/fetch-tags-in-addition-to-normal-refs: (23 commits)
  fetch: improve the error messages emitted for conflicting refspecs
