+margins. Users preferring left-sided stamps may notice that ERC
+also displays the prompt in the left margin, possibly truncating
+or padding it to constrain it to the margin's width. When stamps
+appear in the right margin, which they do by default, users may
+find that ERC actually appends them to copy-as-killed messages
+without an intervening space. This normally poses at most a
+minor inconvenience, however users of the `log' module may prefer
+a workaround provided by `erc-stamp-prefix-log-filter', which
+strips trailing stamps from logged messages and instead prepends
