Compare should not limit the number of commits OR only list the commits

Description

The compare page should not limit the display of commits, but only limit the unified diffs or there should be a way (e.g., by adding a specific CGI parameter), in order to only display all commits.

tortoisegit/tortoisegit@REL_2.3.0.0_EXTERNAL...f9a9e92a just lists 100 commits. Linking to the compare page can be useful e.g., when you want to provide a link so that users can see what changed since a specific version (cf. https://download.tortoisegit.org/tgit/previews/). If users are interested in specific commits, they can easily click on them for comparison - or hide all changesets for files by default. Control using CGI parameters would be lovely.
