Of course, this is to do only if you have not published your changes
yet. And of course another commands exist to revert a patch with a
*new* patch instead of removing it (it is called "rollback" and
automatically records a new patch with a name of
"UNDO: <name_of_old_patch>").

Exactly, just as Darcs' "rollback" command. I just had to do this in tla
(to revert the patch adding --setup to init-tree since it was useless)
a few minutes ago, and did it the obvious way with "replay --reverse"
and "sync-tree" of the same version.

A new flag to "replay" to let patch-logs untouched alltogether? (which
combined with "--reverse" will bring us this useful functionality)
