This branch is for the "checkin without a checkout" feature, a.k.a. "mini-checkin" or "mini-commit". It is a pared-down variant of the checkin command which supports adding or modifying only a single file, and it does so without the requirement of having a checkout database. The main purpose of this feature is to enable web-based editing of files, e.g. embedded documents, and its infrastructure is fully separated from its "control interface" - CLI or web input.

This feature is disabled by default, and enabling it requires setting a comma- or newline-delimited list of filename globs as the fileedit-glob repository setting (part of the "project" group of config options). Those patterns specify the whitelist of files which may be edited with this page. An empty list disables the feature and a single * enables it for all non-binary files. Binary files are rejected by the editor, regardless of the whitelist. The suggestion has been made for the page to offer the ability to upload new versions of binary files, and that will be investigated as soon as it itches someone enough to look into it.
