GNU nano 2.7.5 "Nijntje" can properly search and replace
the \B and \b regex anchors, correctly repaints things
when multiline regexes with identical start and end are
involved, fixes a crash with zero-length regex matches,
does replacements at the edges of a marked region right,
no longer hides double-width characters at the head of
softwrapped rows, displays at most three warnings at
startup, and documents the ability to read a file from
standard input.  Come tickle my ears.
