When the session is restored, the windows are renamed to their original
names switching off automatic-rename, which can be undesirable.
Therefore the value of automatic-rename is now saved for each window and
restored after the renaming.

If the value is set, that value is saved and then applied. Otherwise, a
placeholder of ':' is placed instead, in which case the local option is
unset for that window (as it originally was).

For instance `tmux set-option -g @resurrect-delete-backup-after 1`
to only keep 1 day of backups.

Closes 252.

And make the hook calling simpler at the call site.

This removes (un)zooming on save which should not be necessary anymore
with recent tmux versions (from 2.2 on?).

by find better

remove backup files older than 30 days, but keep at least 5 copies of backup.

Fixes #102.

 This is necessary for zsh.

This reverts commit 6750a88e.

When saving zoomed windows:

- window is un-zoomed
- window layout snapshot is taken
- window is zoomed back

This is done because otherwise tmux does not provide correct window
layout. With this we're working around a tmux bug really.

The above causes an issue with vim. For some reason vim cannot properly
reload it's content when "un-zoom + zoom" is done quickly. Everything
works ok if a little sleep/wait is added, so we're doing just that.
0.1 second sleep seems to be enough.

About `sleep 0.1 || sleep 1`: this is a hack. We want to wait for 0.1
seconds, which seems to be enough to fix the issue. However, according
to POSIX, `sleep` command takes only integers.
BUT, decimal values seem to work everywhere. So, we're using a decimal
value, and if that fails, we behave POSIX friendly.

Related to issue #112.

Add the -J options to `capture-pane` to handle wrapped lines correctly.
This way wrapped lines will be joined upon capture and once restored,
will re-wrap upon pane size changes.

By default only the visible pane area is captured and restored.
The @resurrect-pane-contents-area option lets the full pane area be
captured instead.

This feature is controlled by the '@resurrect-capture-pane-contents'
option.
Currently only the visible area of each pane is saved and restored.

It's faster now.
