Previously, there were many indentation styles in use: Real tabs, 2, 3
or 4 spaces, mixing these within the same file, function or even within
a single line.
This commit changes all bash scripts in the handlers, src and lib dirs
to use consistent indentation: three spaces are now used everywhere.
Other files (e.g. Makefiles) are left untouched.
Additionally, this commit removes all trailing whitespace.
ssh identity file, defaulting to the expected /root/.ssh/id_rsa. This
is important to have if you are trying to backup to a different user
on a backuphost than other handlers are using. For example, if the
rdiff handler is connecting to backalbatross@backupserver-pn using
/root/.ssh/id_rsa for public key authentication, and you want to
configure the maildir handler to connect as user
backmaildir@backupserver-pn you will might want to specify a different
identity file for that authentication (if you do not want to share the
id file between the 'backalbatross' and 'backmaildir' users).
Note: this cannot be accomplished with a ssh config file because that
file is host based, ie. you can only specify one user per host
specified in the config
find: warning: you have specified the -maxdepth option after a
non-option argument -type, but options are not positional (-maxdepth
affects tests specified before it as well as those specified after
it). Please specify options before other arguments.
