commit usage files directly into git the generation of those files was causing us way too much pain to justify automatically generating them all the time. those will have to be re-generated with `build_api` or `build_usage` as appropriate, for example when function signatures or commandline flags change. see #384

commit usage files directly into git the generation of those files was causing us way too much pain to justify automatically generating them all the time. those will have to be re-generated with `build_api` or `build_usage` as appropriate, for example when function signatures or commandline flags change. see #384

Description
~~~~~~~~~~~
Documentation: Explicate that Fnmatch is default This fixes #1247. It also regenerates the usage documentation, so that styling fixex in that section (as well as other existing changes) make it into the files in docs/.

any of the specified retention options. This command is normally used by
automated backup scripts wanting to keep a certain number of historic backups.

Also, prune automatically removes checkpoint archives (incomplete archives left
behind by interrupted backup runs) except if the checkpoint is the latest
archive (and thus still needed). Checkpoint archives are not considered when
comparing archive counts against the retention limits (--keep-*).
If a prefix is set with -P, then only archives that start with the prefix are
considered for deletion and only those archives count towards the totals
specified by the rules.
Otherwise, *all* archives in the repository are candidates for deletion!
If you have multiple sequences of archives with different data sets (e.g.
from different machines) in one shared repository, use one prune call per
data set that matches only the respective archives using the -P option.

The "--keep-within" option takes an argument of the form "<int><char>",
where char is "H", "d", "w", "m", "y". For example, "--keep-within 2d" means
to keep all archives that were created within the past 48 hours.
"1m" is taken to mean "31d". The archives kept with this option do not
count towards the totals specified by any other options.

A good procedure is to thin out more and more the older your backups get.
As an example, "--keep-daily 7" means to keep the latest backup on each day,
up to 7 most recent days with backups (days without backups do not count).
The rules are applied from secondly to yearly, and backups selected by previous
rules do not count towards those of later rules. The time that each backup
starts is used for pruning purposes. Dates and times are interpreted in
the local timezone, and weeks go from Monday to Sunday. Specifying a
negative number of archives to keep means that there is no limit.
The "--keep-last N" option is doing the same as "--keep-secondly N" (and it will
keep the last N archives under the assumption that you do not create more than one
backup archive in the same second).
