Escape autocomplete results for Markdown

Recommend a `-p` while `git fetch`ing

See merge request gitlab-org/gitlab-ce!18016

Especially with the main gitlab repository, there tends to be tons of
stray branches, a continue `git fetch` without any -p will easily lead
to hundreds of "orphaned branches" in the local checkouts.

A label name can contain a `_`, `~~`, or other Markdown-significant
characters. But label references are processed _after_ Markdown processing has
run, so we can't easily fix this on the backend.

We can make it more convenient, though, by changing the frontend to escape these
characters so they aren't processed as Markdown, when we insert them from
autocomplete.

Release notes: https://github.com/libgit2/libgit2/releases/tag/v0.27.0

This version solves a significant performance issue with generating
large diffs: https://github.com/libgit2/libgit2/issues/4460

Timecop was being used in the cycle analytics and burndown seed_fu tasks.
While it seems a little sketchy to use Timecop in this way, this seems like
an exception can be made for test fixtures.
