This commit allows buffers that were not previously written to disk to
be restored if a backup has been generated in their name. Consequently,
we got rid of a few non-POSIX calls to `find` (using `-maxdepth` or
`-delete`), and of the logic that detected the newest backup (which
didn't seem a good reason enough to steer away from a portable command).
Fixes#1236
Purging unused strings could get pretty expensive with a lot of
interned strings as it requiered iterating on all of them. Use
a flag on the refcount of the StringData to see if the string
is interned, and notify the StringRegistry in this case.
This should improve the speed of editing big files with many words,
such as the one described in #1195
Expanding the `kak_assert` macro to either an `if` statement or nothing
leads to issues when the macro is used in a conditional statement that
doesn't use braces.
Example: ncurses_ui.cc:476, in non debug mode, the macro will expand to
an empty line, resulting in the `ungetch` call not being executed if the
`ioctl` call succeeds (line 448).

A change that ended exactly where the previous one started was not
considered backward sorted. Leading to some very bad performances in
certain cases, like '100000o<esc>u'

The Debian implementation of `man-db` does not strip ANSI sequences out
of the file, even though the documentation says it would do so. The
commit that originally closed this issue wasn't related to the problem
experienced, this one hopefully addresses it.
This commit also addresses an issue with the `-i` flag in BSD `sed`
which expects an argument (the GNU implementation doesn't).
Fixes#1098
