Core Rule Set: gitea and Forgejo file and branch names in bodies pass (closes #346)
While SWW_WAF_BODY_LIMIT is set, these body fields skip only the rules
that refused them, on their own paths:

- tree_path, commit_summary and content on the web editor's pages that
  commit a change: edit, new file, delete, upload, patch and
  cherry-pick;
- every field that names a branch, for Windows commands and command
  names: new_branch_name, old_branch_name, old_ref_name, from, to, head,
  base, branch and new_branch;
- message of one file or several changed through the API, for system
  files and Windows commands.

None applies when the query has a parameter of the same name. The
requests were recorded from gitea 1.27.3 and Forgejo 17.0.1.

# The fifteenth change: on Forgejo's paths, some fields skip the rules that
# refused ordinary Forgejo requests there. Forgejo is a fork of gitea, and the
# eighth change's fixes for gitea apply to its requests too, so this file holds
# only what Forgejo sends and gitea does not. Each exclusion runs with the
# request, before the rules it switches off, so this file is loaded before the
# Core Rule Set's rules. Each comment names a request the rule refused.
# Forgejo's search of a wiki sends the text searched for in q, which skips
# these rules there:
# 930120: .htaccess
# 932120: powershell
# 932160: /bin/sh
# 932250: ls -la
# 932260: python3
