templates: add filter to reverse list
The filter supports only lists because for lists, it’s straightforward to
implement. Reversing text doesn’t seem very useful and is hard to implement.
Reversing the bytes would break multi-bytes encodings. Reversing the code
points would break characters consisting of multiple code points. Reversing
graphemes is non-trivial without using a library not included in the standard
library.
Testing recorded "modified" files for merge commit
==================================================
#require execbit
This file shows what hg says are "modified" files for a merge commit
(hg log -T {files}), somewhat exhaustively.
This test file shows merges that involves executable bit changing, check test-merge-combination-exec-bytes.t
For merges that involve files contents changing, check test-merge-combination-file-content.t
For testing of multiple corner case, check test-merge-combination-misc.t
Case with multiple or zero merge ancestors, copies/renames, and identical file contents
with different filelog revisions are not currently covered.
$ . $TESTDIR/testlib/merge-combination-util.sh
All the merges of executable bit.
