- Update to version 2.6.0:
* fixes more than fifty little bugs -- and some of them not so
little.
* It improves moving about in the file browser, corrects failings
of the internal spell checker, adds a new feature
(comment/uncomment lines, with default binding M-3), makes some
error messages clearer, shows more of a file when positionlog
is used and the cursor is near the end, displays all error
messages at startup if there are multiple ones, does not
misinterpret keystrokes when typing very fast, is less eager
to trim the filename on narrow terminals, speeds up
case-insensitive searches, and allows to abort re-searches.
