X Title: Fix diff parsing to support mnemonicPrefix configuration by MirrorDNA-Reflection-Protocol · Pull Request #2092 · gitpython-developers/GitPython

Description: Summary Fixes #2013 When diff.mnemonicPrefix=true is set in git config, git uses different prefixes for diff paths instead of the standard a/ and b/: c/ for commit w/ for worktree i/ for index o/ for object h/ for HEAD Previously, the diff regex and decode_path() function only accepted a/ and b/ prefixes, causing create_patch=True diffs to fail parsing when users had this config enabled. Reproduction As described in #2013: # With ~/.gitconfig containing: # [diff] # mnemonicPrefix = true repo = git.Repo('.') ancestor_ref = repo.merge_base(repo.head, repo.refs['main']) diff = ancestor_ref[0].diff(None, create_patch=True) # Would fail to parse Changes Update re_header regex to accept [abciwoh]/ prefixes instead of just [ab]/ Update decode_path() assertion to accept all valid mnemonic prefixes Add test case for mnemonicPrefix-style diffs Testing New test test_diff_mnemonic_prefix verifies parsing works with c/ and w/ prefixes All existing diff tests pass (except one pre-existing failure on main unrelated to this change) References Git documentation: https://git-scm.com/docs/git-config#Documentation/git-config.txt-diffmnemonicPrefix Issue: #2013
